Appendix C Ohm`s Law, Kirchhoff`s Laws and AC Circuits

... V = IZ (C.17) This is the AC analog of Ohm’s Law for DC circuits. It looks similar to Ohm’s Law for DC circuits, but now the phases of I, V , and Z must be taken into account. Since they have both a magnitude and a phase, then it is clear that V , I, and Z are all vectors. In addition, I and V can b ...

... The root-mean-square (rms) value of an alternating current (or voltage) is that value of the direct current (or voltage) that dissipates power in a resistor at the same rate. In this activity you will determine the rms voltage of an ac resistor circuit and use it to show that its equivalent dc value ...

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.
