سؤال 295

When configured to measure current, how is a multimeter connected to a component?

  1. In seriesپاسخ درست
  2. In parallel
  3. In quadrature
  4. In phase

توضیح

Current must flow through the meter for it to be measured, so the circuit is broken and the meter inserted in series to carry the same current as the component. Connecting a meter set to current in parallel places its near-zero resistance across the component and can blow its fuse or damage it.
