An AC generator of $220\ V$ having internal resistance $r = 10\ \Omega$ and external resistance $R = 100\ \Omega$. What is the power developed in the external circuit

Question

Dr. Abubacker · Accepted Answer

(b) $V = 200V;r = 10\Omega$
$R^{'} = 10 + 100\Omega = 110\Omega$
$I = \frac{V}{R^{'}} = \frac{220}{110} = 2A$
$P = I^{2}R = 4 	imes 100 = 400W$
