Ohm`s Law
... • Property of material that resists the flow of charges (resistivity, ρ, in Ωm) • The inverse property of conductivity • Resistivity is temperature dependent…as temperature increases, then resistivity increases, and so resistance increases. ...

Noise in relaxation oscillators

Noise in these circuits is filtered into a narrow bandwidth by the high-Q frequency-selective elements. This fact allows a relatively simple analysis of the noise in the oscillation, the results of which ...

Using the Optical Port of the 71M6511/71M6513
... When R1 is connected to the collector, the transistor has to “work” to get the output voltage close to zero. However, this circuit has the advantage that no signal inversion occurs. In bench tests it was possible to bridge more than 2” with the circuit from Figure 1, when the IR diode was driven wit ...

3. Power factor measurement in R-L and R
... In a circuit consisting of resistance and inductance connected in series across an a.c.voltage, the supply voltage gets divided into two parts. The voltage across resistance (VR) is in phase with the circuit current while the voltage across inductance (VL) leads the current by 90o. Supply voltage V ...

Current Electricity Lab
... The lab begins with bulbs, but since taking measurements with bulbs can often be imprecise, the measurement portion of the lab uses resistors and a DC power supply. Students will observe these properties of series circuits: 1. The voltage across each resistor can be added to find the voltage across ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
