Calculate the resistance of an electric bulb which allows a $10\, A$ current when connected to a $220\, V$ power source.
Calculate the resistance of an electric bulb which allows a $10\, A$ current when connected to a $220\, V$ power source.
Given $I=10 A , V =220 V , R =?$
Using the relation $V = IR ,$ we have
$R = V / I =220 / 10=22 \Omega$
