The correct answer is: Zero
Ammeter
- An Ammeter is a device which is connected in series of the circuit to find the current.
- Ampere is the unit of current.
- Ammeter is connected in series. So, if it is having a high resistance, it will affect the reading as the current will be reduced in the circuit.
- So, an ammeter should have very small (ideally zero) resistance so that perfect reading can be obtained.
