smallest resistor. - Answers True
The current is the same in all parts of a parallel circuit. - Answers False
The equivalent resistance of two resistors in parallel is equal to their product divided by their sum. -
Answers True
Kirchhoff's second law applies for each current loop in a complex circuit and not just for the total circuit.
- Answers True
Kirchhoff's laws apply only for current loops that contain at least one source of emf. - Answers False
