Question

A human being can be electrocuted if a current as small as 50 mA passes near the heart. An electrician working with sweat hands makes good contact with the two conductors to his holding, one in each hand. If his resistance is 2000 ohm, what might the fatal voltage be?
A) 100 V
B) 50 V
C) 25 V
D) 12 V

Answer 1

Answer:

A) 100 V

Explanation:

I = 50 mA = 0.05 A

We can apply Ohm's Law as follows

V = I*R   ⇒  V = 0.05 A * 2000 Ω = 1000 V
