Question

How is a voltmeter connected in a circuit?

• A. In series with the branch where you want to measure current, with the current flowing into the positive and out of the negative of the device.
• B. In parallel with the branch where you want to measure current, with the current flowing into the positive and out of the negative of the device.
• C. In series with the branch where you want to measure current, with the current flowing into the negative and out of the positive of the device.
• D. In parallel with the branch where you want to measure current, with the current flowing into the negative and out of the positive of the device.

Answer 1

The correct option is D In parallel with the branch where you want to measure current, with the current flowing into the negative and out of the positive of the device.

The voltmeter terminals are connected to the two points across which you want to measure potential. This automatically ensures the device is connected in parallel across the points.
