Question
When configured to measure current, how is a multimeter connected to a component?
Answer Options
- A) In series
- B) In parallel
- C) In quadrature
- D) In phase
Correct Answer: A
Explanation
When a multimeter is configured to measure electrical current (acting as an ammeter, T7D04), it must have extremely low internal resistance. This is because all of the current flowing to the load must pass through the meter for the measurement to be accurate.
Therefore, an ammeter is always connected in series with the component or load. This connection requires breaking the circuit and inserting the meter in the path of the current flow.
