How is the voltmeter connected in all circuits to measure the voltage between two points?

Correct option is A

The correct answer is (a) In parallel.
· A voltmeter is connected in parallel to the circuit to measure the voltage between two points.
· This is because it needs to measure the potential difference across the components without altering the current flowing through the circuit.
· If it were connected in series, it would interfere with the circuit's operation and provide inaccurate readings.
Information Booster:
· A voltmeter has a high resistance to ensure it doesn't draw current from the circuit.
· This allows for accurate measurement of the voltage without affecting the circuit.
