[-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER Data for current versus potential-difference (voltage) is collected for a resistor and is shown in the figure below. Each interval along the horizontal, electric potential axis is 10. V, and each interval along the vertical, current axis is 2.0 A. The resistor is 'ohmic', meaning that it satisfies Ohm's law. What is the resistance of this resistor? I (A) - AV (V) 2. [-/4 Points] DETAILS MY NOTES ASK YOUR TEACHER 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 500 k$2. If you accidentally touch both terminals of your 115 V household electricity supply with dry fingers, what current will flow, and will you receive a dangerous shock? |mA, a ---Select--- V|shock. (b) If your hands are moist, your resistance drops to approximately 1.7 k$2. If you accidentally touch both terminals of your 115 V household supply with moist fingers, what current will flow, and will you receive a dangerous shock? mA, a ---Select--- V|shock
