The human body can exhibit a wide range of resistances to current depending on the path of the current, contact area, and sweatiness of the skin. suppose the resistance across the chest from the left hand to the right hand is 1.85 ✕ 106 ω. (a) how much voltage is required to cause possible heart fibrillation in a man, which corresponds to 360 ma of direct current?

Explanation:

As we know that resistance offered by the body from left hand to right hand is given as

now the current flowing through the body is given as

now in order to find out the potential difference across the hands that is applied is given by ohm's law

V = i R

so the applied voltage across the hand must be given as above

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
