Answer to Question #205575 in Physics for Minahil Mirza

Question

In a parallel circuit a 50 ohm hairdryer has 2.4 amps of current flowing through it. How much current is flowing through a light bulb which is in parallel with the hairdryer?

Answer 1

$V=IR=2.4\cdot50=120\ (V)$

Suppose that the power of the lamp is $12\ (W)$ . So,

$I=P/V=12/120=0.1\ (A)$ . Answer
