Ahuman 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?

Fatal voltage will be 1000 volt

Explanation:

We have given that current is very small as

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

So fatal voltage will be

So fatal voltage will be 1000 volt

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
