Solve the following using the GRSA Method. Thanks in advance! 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. 2. In a circuit, the potential drop across the 10 k- resistor is 100 V. What is the current through the resistor? 3. A coffee cup immersion heater utilizes a heating coil with a resistance of 8.5 . Determine the current through the coil when operated at 110 V. 4. An electronic device has a resistance of 20 ohms and a current of 15 A. What is the voltage across the device? 5. A 3V potential difference is applied across a 6 resistor. What is the current that flows into the resistor? 6. A current of 0.2A passes through a 1.4k resistor. What is the voltage across it? 7. An electric heater has a coiled metal wire which draws a current of 100 A. The resistance of the wire is 1.1 ohms. Calculate the voltage that must be established for it. 8. Compute the resistivity of the given material whose resistance is 2 ; area of cross-section and length are 25cm2 and 15 cm respectively
