Ohm's Law is at the very core of all electrical and electronic circuits.
It links potential difference with current and resistance in a linear circuit.
Ohms Law states that the current flowing in a linear circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit.
So for a linear circuit, if the voltage doubled, the current will double, but if the resistance is doubled the current will fall to a half.
This can be expressed mathematically as V=IR, where V is potential difference in volts, I is current in amps and R is resistance on Ohms. So if we know the current and resistance, we can calculate the potential difference.
We can easily manipulate the equation to give R = V/I and I = V/R
So there we have it a simple summary of Ohms Law. If you need any more, head over to our web page or our longer video - links are in the description.
