Question

a restance is 15 ohm has a current of 5 amperes flowing in it.what potential difference is there between its end.

Answer 1

75 v by using the formula
v=ir

Answer 2

Formula used: V = iR
where V = Potential difference across the ends
            i = current flowing through the circuit
            R = Resistance offered.

According to the given data,
V = ?, i = 5 A, R = 15Ω

Substituting the values in the given formula,
                           V = iR
                           V = 5 x 15 = 75 v

Therefore, Potential difference across the end = 75 v
