Question

The emf of a battery will normally be greater, equal, or less than the ddp that it supplies to the circuit?

a) Greater
b) Equal
c) Less
d) Depends on the type of battery

Answer 1

The emf of a battery is normally greater than the ddp it supplies to the circuit due to internal resistance and external resistance.

Step-by-step explanation:

The emf of a battery will normally be greater than the ddp that it supplies to the circuit. This is because the emf represents the maximum voltage that the battery can supply, while the actual voltage across the terminals of the battery will be less due to the internal resistance of the battery and any external resistance in the circuit. For example, when current flows through the battery, the voltage across the terminals will decrease.
