Danger of electrical shock depends on body resistance (100 kΩ dry, 1 kΩ wet). 10 mA causes a slight shock; 1.0 A can cause death.

A boy touches one terminal of a 12 V car battery with his right hand and the other terminal with his left hand simultaneously. Calculate the current flowing with dry hands and with wet hands, and state what effect, if any, the current has on the boy in each case.
