We often say “a current is going through the wire”. What goes through the wire, the charge or the current?

A non-ideal battery is connected to a resistor. Is work done by the battery equal to the thermal energy developed in the resistor? Does your answer change if the battery is ideal?

Sometimes it is said that “heat is developed” in a resistance when there is an electric current in it. Recall that heat is defined as the energy being transferred due to the temperature difference. Is the statement under quotes technically correct?

Would you prefer a voltmeter or a potentiometer to measure the emf of a battery?

Does a conductor become charged when a current is passed through it?
