Question

A human being can be electrocuted if a current as small as 50 mA passes near the heart. An electrician working with sweaty hands makes good contact with the two conductors he is holding, one in each hand. If his resistance is 2000 Ohm, what might the fatal voltage be?

Answer 1

Answer:

The fatel voltage is 100 volts.                              

Explanation:

Given that,

Current passes near the heart is, $I=50\ mA$

An electrician working with sweaty hands makes good contact with the two conductors he is holding, one in each hand.

Resistance, R = 2000 ohms

We need to find the fatal voltage. It can be calculated using Ohm's law as :

$V=IR\\\\V=50\times 10^{-3}\times 2000\\\\V=100\ V$

So, the fatel voltage is 100 volts. Hence, this is the required solution.
