If you touch the two terminals of a power supply with your two fingertips on opposite hands, the potential difference will produce a current through your torso. The maximum safe current is approximately 5 mA.
(a) If your hands are completely dry, the resistance of your body from fingertip to fingertip is approximately 535 kΩ. If you accidentally touch both terminals of your 125 V household electricity supply with dry fingers, what current will flow, and will you receive a dangerous shock?
___mA
(b) If your hands are moist, your resistance drops to approximately 2.5 kΩ. If you accidentally touch both terminals of your 125 V household supply with moist fingers, what current will flow, and will you receive a dangerous shock?
__mA
(c) For the situation of part a, what electric power is dissipated in your body?
__mW
Would you notice the heating?
yes or no
