Question

When measuring voltage, the voltmeter must be connected:

A) In parallel
B) In series
C) In circuit
D) Across the power source

Answer 1

A voltmeter needs to be connected in parallel to measure voltage.

Step-by-step explanation:

A voltmeter needs to be connected in parallel to measure voltage.

When measuring voltage, the voltmeter is connected in parallel to the power source or any other component of the circuit.

Connecting the voltmeter in parallel ensures that it measures the same potential difference as the component being measured.
