How can the range of an ammeter be increased?
- A By adding resistance in series with the circuit under test
- B By adding resistance in parallel with the circuit under test
- C By adding resistance in series with the meter
- D By adding resistance in parallel with the meter
Correct answer: D — By adding resistance in parallel with the meter. From the official ISED question bank, verified word for word.
Why
To measure more current than the meter can handle alone, you add a resistor in parallel with the meter. The full explanation — and one for every question — is in Pro.
