How is an voltmeter connected in a circuit.how is an voltmeter is connected in a circuit?

A voltmeter is connected in parallel to the component or section of the circuit where the voltage is to be measured. This parallel connection allows the voltmeter to measure the potential difference across that component without significantly affecting the circuit's performance. It's important to ensure that the voltmeter has a high internal resistance to minimize the current flowing through it and avoid loading the circuit.
