Question

An electric bulb of resistance 480 ohm is connected to 220 volt. Find the amount of electric energy consumed in 10 seconds

Answer 1

Hi..

Hope this helps u!!

Answer 2

As per the question, the resistance of the bulb [R] = 480 ohm.

The electric volt [v] = 220 volt

The consumption time [t] = 10 seconds.

We are asked to calculate the electric energy consumed by the ball.

                   $The\ electric\ energy\ E\ =\frac{v^2t}{R}$

                                                                $=\frac{[220]^2*10}{480} \ J$

                                                                $=1,008.333...J$

                                                                $=1,008.33\ J$     [ANS]
