Question

I'll mark u as brainliest if you answer this question.why is voltmeter always connected in parallel across the two points between which the potential difference is to be measured?

Answer 1

A voltmeter must be connected in parallel to measure the voltage of a device because objects in parallel experience the same potential difference. A voltmeter is used to measure the electrical potential difference between two locations in an electrical circuit.

Answer 2

Voltage means Potential difference between two points.
V=IR ( ohms law)
Voltmeter provides very high resistance .

When voltmeter connected in parallel ..so no current flowing through it due to very high resistance.. Voltage drop will occur..we get same voltage so its indicates voltage.
