When you look at the Ohm’s Law Wheel, select this formula: I = W/E (amps = watts volts); I = 5,000 watts by 240 volts; I = 20 ...
(It’s called Ohm’s Law.) For example, if you know the voltage drop across a known value of resistance, you can work out how much current must be passing through the resistor. Let’s look at an example ...
As free electrons flow through wires, they collide with the ions in the wire which causes the ions to vibrate more. This increased vibration of the ions increases the temperature of the wire ...
