Why voltmeter is connected in parallel not in series?
Answers
Explanation:
voltmeter to measure a device's voltage, it must be connected in parallel to that device . This is necessary because objects in parallel experience the same potential difference. n ammeter measures the electric current in a circuit. ... This is necessary because objects in series experience the same current.
Explanation:
The internal resistance of voltmeter is very high or infinite. When it is connected in parallel, very less or negligible current flows through the voltmeter and it does not disturbs the original circuit without voltmeter.
If it is connected in series, the effective resistance of the overall circuit will be very high and almost no current will flow in the circuit, which is an undesired condition.
So voltmeter is always connected in parallel.
