How is current related to voltage in a circuit?

Current is directly proportional to voltage in a circuit.

Explanation:

Given that,

voltage of circuit = V

resistance of circuit = R

current of circuit = I

The ohms law shows that voltage is directly proportional to both the amount of current flowing in the circuit and the resistance. Hence, Ohms law is mathematically expressed as:

V α IR

V = IR

Thus, an increase in current (I) will lead to a corresponding increase in voltage (V) of the circuit provided resistance remains the same, while a decrease in current will also cause voltage to decrease.
