Phase is the timing relationship between two different sine waves. If two generators are connected across a given load in series, and if their armatures begin rotating together at exactly the same time and speed, two different alternating voltages will be produced. In...
No matter which way we turn or twist the wire, the left hand rule applies. But what happens if we put a loop in the wire? When the wire is looped, as you will see from the on the right, the little magnetic fields that wrap around the wire cross through each...
There are various ways to produce electricity. We can produce electricity chemically with a battery or electricity can be produced mechanically by a generator. It is important understand difference between electricity produced by a battery, and electricity produced by...
AMPLITUDE: The magnitude of change in a varying quantity from it’s zero value. Usually measured in Voltage, or deciBels, can denote volume. ATOM: The smallest particle of an element that shares the properties of that element. They consist of ELECTRONS, PROTONS,...
Class C Amplifiers You will recall that most AF amplifiers use cathode bias. The audio amplifier tubes are operated ad Class A or Class B, because we are interested in obtaining good fidelity. The Class A amplifier sacrifices efficiency for fidelity. In the case of an...
