Question # 1
Why the resistance of an ammeter should be very low?
- Ans 1: Am ammeter is connected in a series with a circuit to measure the current,It is connected in series so that total current passing through the circuit should pass through it.If the resistance of the ammeter will be large,it will alter the current of the circuit to great extent and the measurement of current will not be accurate.
