How much current will an electric bulb of resistance $1100 \ \Omega$ draw from a $220 \ V$ source? If a heater of resistance $100 \ \Omega$ is connected to the same source instead of the bulb,calculate the current drawn by the heater.

(0.2 A, 2.2 A) According to Ohm's law,the current $I$ is given by the formula $I = \frac{V}{R}$.
For the electric bulb:
Given,$V = 220 \ V$ and $R = 1100 \ \Omega$.
$I = \frac{220}{1100} = 0.2 \ A$.
For the electric heater:
Given,$V = 220 \ V$ and $R = 100 \ \Omega$.
$I = \frac{220}{100} = 2.2 \ A$.
