A 12 volt car battery is being used to power a circuit with a total resistance of 0.5 Mega-ohm. a) What is the power (in watts) being used by this circuit? b) The circuit is switched on for exactly 27.3 days and then switched off. How much energy has the circuit used (in joules AND kilowatt-hours) in this time? c) If the current rate of hydro use is 10.1 cents per kilowatt-hour, how much would the use of this circuit contribute to your hydro bill (assuming that no other charges apply)?
