Answer to Question #320303 in Electric Circuits for Deirdre

Question

While repairing an electric bulb socket, an electrician gets a mild shock when a

current of 0.005 A passes through him. The same electrician is killed by a current of 0.15 A when he turned on an electric bulb while taking a bath. The voltage in each situation is equal to 120 V. Find the resistance of the electrician in each situation.

Answer 1

Solution;

From Ohms law;

$V=IR$

Therefore;

$R=\frac{V}{I}$

Situation 1:

I=0.005A

V=120V

Therefore;

$R_1=\frac{120}{0.005}=24000\Omega$

Situation 2:

I=0.15A

V=120V

$R=\frac{120}{0.15}=800\Omega$
