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.
