If a 12-V battery,with negligible internal resistance,and an 20-Ω resistor are connected in series,what is the amount of electrical energy transformed to heat per coulomb of charge that flows through the circuit?

Question

Quizplus · Accepted Answer

The electrical energy transformed to heat per coulomb of charge is equal to the voltage of the battery, which is 12 V, hence 12 J per coulomb.
