Why is the "Voltmeter connected parallel to the resistor"? Explain.
Why is the "Voltmeter connected parallel to the resistor"? Explain.
Dear student, Voltmeter measures the potential difference, and it has high internal resistance. As the voltmeter is connected in parallel with a circuit component, the amount of current through the voltmeter is very less. Therefore, the current through the circuit is not altered.
So, the voltmeter always connected in parallel with the circuit.
A voltmeter is always connected in parallel because if it is connected in series, it will change the value of potential difference to be measured by minimising the current in the circuit as it has very large resistance and hence will give faulty reading. Connecting it in parallel will not change the value of potential difference being measured as the voltmeter will draw negligible current and hence give correct reading of potential difference.
Hope it helps
Best wishes!
