John is changing a lightbulb in a lamp. It's a warm summer evening, and the resistance of his damp skin is only 3600 Ω . 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 . What is the current through his torso?

John is changing a lightbulb in a lamp. It's a warm summer evening, and the resistance of his damp skin is only 3600 Ω . 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 .

What is the current through his torso?
 
Arm: 310

Leg: 290
Rakin,
Wherever
current enters or
leaves the body,
we add the skin
resistance.

When current traverses
the torso between any
two points (arm to arm,
arm to leg, leg to leg), this
adds a resistance of 30 f.
