Question

An electric bulb is connected to 200 volts if the current of passes of 0.5 passes through it what is the power of the bulb​

Answer 1

Answer:

We know that, power is basically work done in unit time.

That is, Power=work/time

And, work=potential different × charge

And, charge= I×t (current passing through a conductor in unit time)

Therefore, power=(potential difference×charge)/(charge/current)

=potential difference×current

=200V × 0.5A

100watt.
