Question

How much current will an electric bulb draw from 220 V source if the resistance of the bulb is 1200 ?If in place of a bulb,a Ω heater of resistance 100 is connected to the sources,calculate the current drawn by it?

Answer 1

Answer:

in first case current withdraw by bulb, and in second case current withdraw by heater

Answer 2

Answer:

For the electric bulb:

V = 220 V.

R = 1200 Ω.

Using Ohm's law,

V=IR

220 = I × 1200

220/1200 =I

I =0.183 A

For the heater:

R = 100 Ω.

V = 220 V.

Using Ohm's law,

V= IR

220= I×100

220/100= I

I =2.2A
