How is a voltmeter connected in the circuit to measure the potential difference between two points?
उत्तर
A voltmeter is always connected in parallel across the points where the potential difference is to be measured.
Suppose we have a conductor AB, such as a resistance wire, and we want to measure the potential difference across its ends.
So one end of the voltmeter is connected to point A and the other end is connected to point B. We can read the value of the potential difference in volts on the dial of the voltmeter.
