Practice question · True or false
A current meter must carry the full current and add almost no resistance.
Hints
- Where must a current meter sit relative to the component?
- It must carry the same current, and add as little resistance as possible.
Show the answer
True
Why
True, an ammeter must carry the current it measures, so it goes in series, and its resistance must be small or it reduces that current. Connecting one in parallel instead is close to a short circuit.
