ohms law

Ohms law links the current, voltage and resistance of a circuit together. It is represented by this equation:

V=I x R

The formula can be rearranged to find different variables. Remember, current is represented as I, voltage as V and resistance by R.

The three variables are related, so changing one will change another is a predictable way.

Voltage is directly proportional to current B. By increasing the volume, we increase the current.

If we increase the resistance, we have to increase the voltage to maintain a constant current. This means voltage is directly proportional to resistance

Current is inversely proportional to resistance. If the resistance is increased, the current in a circuit will decrease
