what resistance would produce a current of 120 amps from a 6-volt battery
A 36.0 volt battery causes a current of 0.632 amps to flow through a resistor. By first finding the power dissipated by the bulb, how many joules of energy does the battery lose in a minute? Please explain how the answer is 1365.1 J
A 12-volt electric accumulator supplies a current of 10 amps at a resistance for 0.20h. a) indicate if the accumulator develops a positive, negative or zero work during the process. b) if the system includes both the accumulator and the resistance, indicate whether the work is positive, negative or zero.
