A human being can be electrocuted if a current as small as 48 mA passes near the heart. An electrician working with sweaty hands makes good contact with the two conductors he is holding. If his resistance is 2100 Ω, what might the fatal voltage in volts be?

V = 100.8 V

Explanation:

given,

hum being can be electrocuted with current = 48 mA = 0.048 A

Resistance of the man = 2100 Ω

Fatal voltage = ?

we know,

V = I R

V is the fatal voltage in Volts

R is the resistance provided by the human body

I is current

V = I R

V = 0.048 x 2100

V = 100.8 V

the voltage which can be considered as fatal is equal to V = 100.8 V
