You buy a AA battery in the store,and it is marked 1.5 V.If this marking is strictly accurate,while this battery is fresh
A)its terminal voltage will be more than 1.5 V when it is used in a circuit.
B)its terminal voltage will be less than 1.5 V when it is used in a circuit.
C)its terminal voltage will be 1.5 V when it is used in a circuit.

Question

Quizplus · Accepted Answer

The terminal voltage of a battery under load (when it is used in a circuit) is typically less than its no-load voltage (the voltage when it's not connected to a circuit) due to internal resistance. Therefore, when a fresh AA battery marked 1.5 V is used in a circuit, its terminal voltage will be slightly less than 1.5 V.
