If water is moving through a hose, we say that it has FLOW. If we restrict the flow, by pinching the hose, we are causing friction at the point of restriction. This friction can be said, is resistance to the flow of the water. Electricity, according to Benjamin...
Example for a Carbon 22000 Ohms or 22 KiloOhms also known as 22K at 5% tolerance: Band 1 = Red, 1st digit Band 2 = Red, 2nd digit Band 3 = Orange, 3rd digit, multiply with zeros, in this case 3 zero's Band 4 = Gold, Tolerance, 5% Example for a Precision Metal Film...
We have already discussed current, resistance, and voltage. Now we shall discuss the important relationship that exists between the three. Around 1840, German physicist Georg Ohm noted that there was a distinct mathematical relationship between Voltage, current and...
The formula for inductors in parallel: When AC is applied to a coil, a varying magnetic field will be produced around it. When another coil is placed within that magnetic field, it will induce a current flowing in that coil. This principle is called MUTUAL INDUCTANCE...
In this circuit, we have a resistor, a capacitor, and a coil in series. Because the coil and the capacitor act in an opposite manner, they tend to cancel each other out. We say that the coil is additive, and the cap is subtractive in nature. If the inductive...
Conductor is the name assigned to a broad catagory of materials through which a practical amount of electric current can flow under normal conditions. Most conductors are metallic. The usefulness of metal to conduct electric current stems from the abundance of free...
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 other's...
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, and...
