Question

John is changing a lightbulb in a lamp. It's a warm summer evening, and the resistance of his damp skin is only 3600 ? . While one hand is holding the grounded metal frame of the lamp, the other hand accidentally touches the hot electrode in the base of the socket. The voltage of the socket is 120 V . Use the data shown in

What is the current through his torso?

Arm: 310 Arm: 310 Rakin Rakin Torso: 30 Leg: 290 Leg: 2900 Rskin Rakin Wherever current enters orthe torso between any leaves the body, two points (arm to arm, we add the skinarm to leg, leg to leg), this resistance When current traverses adds a resistance of 30 .

Explanation / Answer

given

Rskin = 3600 Ohm

Now , for the Hands touching live and ground wire

In series ,

Rs = 3600 + 3600 + 310 + 310 + 30

Rs = 7850 Ohm

using Ohm's law

V =I*R

120 = I * 7850

I = 0.01528 A, thus the the current throught the torso is 0.01528 A
