What happens to the current in a closed circuit if the potential difference is increased and the resistance remains consistent?

If the potential difference (voltage) across a closed circuit is increased while the resistance remains constant, according to Ohm's Law, the current through the circuit will also increase.

Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) applied across the conductor, and inversely proportional to the resistance (R) of the conductor. The mathematical representation of Ohm's Law is:

I = V / R

In this scenario, if we keep the resistance constant and increase the potential difference across the circuit, the ratio V/R will become larger. Since the numerator (V) is increasing while the denominator (R) remains constant, the result is a larger value for I (current).

To summarize, an increase in potential difference will cause an increase in current provided that the resistance remains constant in a closed circuit.
