Question

Electric bulb rated 22w &220volt find resistance

Answer 1

Answer:

The electric bulb is having power of 22 Watt and having potential of 22 Volt we get these information from the question.

The formulae of the power of the electric bulb is power (P)=V^2/R.

So, if we place all the values in the formulae we will get the value of resistance R to be 220*220/22 = 2200 ohm.

So, the resistance of the electric bulb will be 2200Ω.
