How is an ammeter usually connected to a circuit under test?
- A In parallel with the circuit
- B In series with the circuit
- C In quadrature with the circuit
- D In phase with the circuit
Correct answer: B — In series with the circuit. From the official ISED question bank, verified word for word.
Why
An ammeter measures the flow of electric current, which is the same amount of electricity passing through every point in a single path. The full explanation — and one for every question — is in Pro.
