Solve the following problem in the paper then answer it correctly. GIVEN: REQUIRED: SOLUTION: ANSWER: 1. A stun gun or TASER is designed to put out a few seconds worth of electric pulses that impress a voltage of about 1200 V across the human body. This results in an average current of approximately 3 mA into a human body. Using these figures, estimate the resistance of the human body.

What is the voltage change if you cross a resistor R in the same direction as the current I? (This means you want Vf-Vi, where Vi is the voltage where the current enters the resistor and Vf, is the voltage where the current leaves the resistor.) What is the voltage change if you cross a resistor R opposite the direction of the current I? (in this case, Vi is the voltage where the current leaves the resistor, and Vf is the voltage where the current enters the resistor.) Which answer is correct? +IR in both cases +IR in the first case and -IR in the second case. +IR in both cases -IR in the first case and +IR in the second case.
