Question

Potential difference between the ends of a wire is 1.5volts on passing current through it, 15joules energy is obtained in 20sec. Calculate the current flowing in the wire

Answer 1

Answer:

0.5 A

Explanation:

POWER = WORK DONE ÷ TIME

P = W/T

P = 15÷20. P = 0.75 W

ALSO,,, P = V × I

0.75 = 1.5 × I

I = 0.75÷ 1.5

I = 0.5 A
