5. In the lecture, I described Joule's use of an electric generator to heat a mass of water. Instead of a generator connected to a resistor, let there be a 12V battery connected to a 30 resistor. a) How much current will run through the circuit? b) If the heat generated by an electric circuit is given by: P = I²R how long would it take to raise 1 gallon of water by 1 degree celsius? (FYI, amps squared multiplied by ohms reduces to the units joules/second)
