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 0, what might the fatal voltage be?

Answer 1

Fatal voltage will be 1000 volt

Step-by-step explanation:

We have given that current is very small as
`i=50 mA=50* 10^(-3)A`

Resistance is given as R = 20000 ohm

We have to find the fatal velotage

According to ohm's law

We know that voltage is given by
`V=iR`

So fatal voltage will be
`V=50* 10^(-3)* 20000=1000volt`

So fatal voltage will be 1000 volt
