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 the voltage increases the current increases in direct proportion. This is known as Ohm’s Law. Key fact Ohm’s Law state that the voltage across a conductor is directly proportional to the ...
