How many electrons pass a given location in the circuit

Reference no: EM13237773

A car's starter motor draws 59 A from the car's battery during startup. If the startup time is 2.1s, how many electrons pass a given location in the circuit during that time? A single electon has a charge of 1.602177 x 10^-9. What is the emf of a battery with a 0.19 ohm internal resistance if the battery delivers 1.5A to an externally connected 6.0 ohm resistor? Consider a 1.40 kW hair dryer operated on 120V what is current? its resistance?
