how much current will an electric bulb draw from 220v source if the resistance of the bulb is 1200ohm .if in place of bulb a heater of resistance 100ohm is connected to the sources .calculate the current drawn by it?

Hello Mate! Here is your answer!

Given,

Potential Difference (V) = 220V

Resistance (R) = 1200 Ohm

V = IR .... where 'I' stands for current

= 220 = 1200I

= 0.1834 A = I

In the second case,

V = 220 V

R = 100 Ohm

V = IR

= 220 = 100I

= 2.2 A = I

I hope this helps.
