Safety warnings
Safety warnings
This is a tutorial aid to implement laboratory works in electronics. The students are
expected to have acquired knowledge of electronic components, electrical wiring,
and electrical schematic symbols [1]. The manual complies with the curriculum and
the syllabus of the course AAR3320 “Electronics and Semiconductor Engineering”
[2], [3]. The laboratory has dangerous equipment whose voltages above 60 VDC or
30 VAC can pose a shock hazard, therefore read carefully the following safety
warnings and respect all the safety precautions.
1. Never apply the mains power if it may cause a danger or an injury. In the case of
an accident, switch off the nearest safety switch and release the sufferer from the
voltage. Thereafter call the rescue service (numbers 112 and 0112) and provide
the first aid.
2. In the case of overheating, smelling, the sparkles or electric arc between
contacts, switch off the supply immediately. Additional red safety push-button is
located on the front panel of the main laboratory switchboard. In the case of an
emergency, press this button to switch off all the lab benches. After avoiding an
emergency, pull out this push-button to restore the supply.
3. To avoid an electric shock, never switch on the supply without the instructor’s
permission, never open the covers, and do not touch with wires while the circuit is
powered.
4. Enable free access to the feeder board, lab bench, emergency switches, and all
the devices, which are adjusted during the experimentation. All equipment and
appliances should be well visible and their displacement or pulling down from the
table should be avoided.
5. When assembling the circuits, connect no more than two conductors to one
terminal or socket. To change the circuit, switch off the power.
6. Before energizing the lab bench, make sure that all devices and measuring
instruments are suitable for operation throughout the voltage and current ranges
provided by this manual. Do not run the circuits over the rated voltages and
currents and do not allow their overloading. Do not use equipment if it looks
damaged or operates abnormally.
7. It is prohibited to lean and sit, to hang clothes, to place bags, cases etc. on the
workplaces, to leave and to enter the laboratory without the instructor’s
permission, to eat, drink and smoke in the laboratory, to touch the devices not
needed for the given work, and to implement the experiments alone.

Preliminary notes
Preliminary notes about the workflow
Circuit preparation
1. Every student should implement the mandatory part of the works and may employ
the optional part given in small print in this tutorial aid.
2. Prepare for a work beforehand. Using the annexes of this manual, find the data
of the studied semiconductor devices, resistors, and the breadboard layout.
3. Basing on the schemes shown in Fig. 1, develop the principal circuit diagram for
experimentation. Each circuit includes a studied semiconductor device and
voltage dividers. Restrict the supply voltage Us = 10 V and set its polarity
accordingly the component data. Limit the power consumption of every part P ≤
1 W. Calculate the buffer resistors R1 to limit the current through a component.
Connecting a semiconductor without such resistors is a sure-fire way to kill it! To
adjust the voltage U2 across the component, apply the potentiometers R2 of 1 kΩ
or 10 kΩ. Therefore,
R1 ≥ max { Us / Imax; Us2 / P }
P1 ≥ Us2 / R1
I1 ≤ Us / R1

4. Add a circuit to indicate whether the scheme is energised using a LED and a
resistor:
RLED ≥ (Us – ∆ULED) / ILED
PLED ≥ ILED2⋅RLED
5. To estimate the voltages and currents, supplement your circuit with meters. Use
the digital multimeter or a voltmeter to measure the voltage across two leads. To
this aim, place the positive terminal on the lead with higher voltage (if known) and
the negative terminal on the lead with a lower voltage. A digital multimeter can be
used as an ammeter to determine the current flow through a wire or electrical
component. This measurement is accomplished by placing the multimeter or the
ammeter in series with the wire that the current is flowing through. Draw expected
characteristics.

Preliminary notes
Wiring
1. Develop the wiring diagram. Every workplace is accomplished with a breadboard,
a board with a studied device, a power supply, and measuring devices.
Converting the principal circuit to a wiring diagram, example of which is shown in
Fig. 2, is not straightforward because the arrangement of components will look
quite different from the principal circuit.

2. Place the resistors, potentiometers, and LED on the breadboard layout. Use the
clip rows for the parts those thin leads do not exceed 0,6 mm in diameter and the
clip columns at the foot of the breadboard for the potentiometers and resistors
with thicker leads.
3. Link the components routing the jumper wires around the parts, not over them
thus making changing the components easier when needed. Wire the red positive
supply socket of the breadboard with a red bus strip and the black negative
supply socket with a black bus strip. Do not insert the component leads to the bus
5
Preliminary notes
strips; instead, use the jumper wires to wire the bus strips with the leads pushed
into the clips.
4. Apply the blue and green sockets to wire the emitter and collector of the
transistor board or the anode and cathode of the diode and thyristor boards. Use
the yellow socket to wire the control leads (base, gate).
5. Connect also the external board of a studied device, the supply, the measuring
devices, and the signal generators (if required) to these sockets.
Experimentation and reporting
1. Assemble the circuit accordingly the wiring diagram by pushing the component
leads to the breadboard clips. Keep the jumper wires on the board flat, so that the
board does not look cluttered.
2. Provide the link-up of the breadboard with the board of a studied device and the
measuring devices using the coloured cord set of special safety wires belonging
to the workplace outfit. Choose the red wires for the positive polarity and the black
ones for the negative polarity.
3. Before experimentation, check all the connections carefully. Make sure that
semiconductor devices are the correct way round and no leads are touching
(unless they connect to the same block).
4. When selecting the measuring range of the meters, ensure that the maximum is
above the expected reading anticipated. Selection of a high range prevents the
meter overloading. When the range of the value to be measured is unknown, set
the highest possible range or, wherever possible, choose autoranging.
5. Adjust the supply voltage to about 10 V and then turn off the power with the
pushbutton. After that, connect the breadboard to the positive (red) and negative
(black) terminals of the power supply and press the pushbutton to test the circuit.
If your circuit does not work, deenergize the breadboard and very carefully recheck every connection against the circuit diagram.
6. In experimentation, change the voltages by potentiometers and measure voltages
and currents. Any overvoltage, overcurrent, and overheating are prohibited!
During the measuring you can optimise the meter range for the best reading. If
possible, enable all the leading digits to not read zero, and in this way the
greatest number of significant digits can be read.
7. Before changing functions or experiments, power off the breadboard. Never
perform resistance or continuity measurements on live circuits!
8. At the end of experimentation, submit the protocols and other results to the
instructor. After instructor’s permission, take off the circuit, switch off and return
the measuring devices and equipment onto their places, and leave the workplace
in order.
9. Every student must prepare and defend the personal report about every work.
The report includes the title sheet, protocols, tables of experiments, calculations,
diagrams, and conclusions. In conclusions, evaluate compliance of the results
with the theoretical aspects and valid standards, and expediency of the used
methods. Pay attention to the differences of the results obtained, experimental
errors, mistaken measurement readings, and their reasons.
