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...
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...
