```ECET 102 : Electrical Circuits I
Test 1
Name : ........................................................................
Q1.
Figure Q 1
For the series DC circuit shown in figure Q 1
1. Find the total resistance RT across point ‘a’ and ‘b’
2. Find the source current IS and indicate the direction in figure Q 1
3. Using Ohm’s law find voltage across each resistor: VR1, VR2, VR3, and VR4. Clearly indicate
the polarity in figure Q 1
4. Find power dissipated by each resistor PR1, PR2,PR3, and PR4.
5. Find the total power produce by the source (PS).
6. If the circuit was connected for 20 s, what is the energy produced by the source during
that time period (ES)
Q2
Figure Q 2
For the circuit in figure Q 2
1. Write Kirchhoff’s Voltage Law (KVL) in terms of known voltages, known resistance and
current.
2. Solve the KVL equation to find the current in the circuit and clearly indicate the
direction.
3. Find voltage across each resistor VR1, VR2 and VR3 and clearly indicate the polarity
Q3
Figure Q 3.1
For figure Q 3.1
1. Use Voltage Divider Rule (VDR) to find the voltages across each resistor V R1, VR2, VR3, and
VR4. Indicate the polarity
2. Using any method you think is appropriate, find the current through all the resistors.
3. Assume you have given a 12 V battery and a bulb operated in 3 V. You are going to
create the circuit in figure Q 3.2 to get the 3 V to the bulb.
Figure Q 3.2
Calculate the ratio of resistors (R1/R2)
Q4
Figure Q 4
For the circuit in figure Q 4
1. Using appropriate technique find Va, Vb, Vc, and Vd
2. Hence find Vab, Vbd, and Vdc
3. In figure Q 4 you want to measure
a. Current through resistor R1
b. Voltage across resistor R2
c. Voltage at point b
Redraw the circuit showing how you are going to connect multi-meters to measure
current (as ammeter) and to measure voltage (as voltmeter) . Draw three different
circuit for three scenarios (part a, b and c).
