If the potential difference at the ends of a conductor with a resistance of 5 Ohm = 12V, then what is the current in the circuit?

R = 5 Ohm – resistance of some conductor;

U = 12 Volts – potential difference at the ends of this conductor (electrical circuit voltage).

It is required to determine I (Ampere) – the value of the current in the electrical circuit.

To determine the value of the current strength, you must use the following formula (Ohm’s law):

U = I * R, from here we find that:

I = U / R;

I = 12/5 = 2.4 Amperes.

Answer: the current in the electrical circuit is 2.4 Amperes.
