A voltmeter is an instrument used to measure the electric potential difference (voltage) between two points in an electrical circuit.
A voltmeter is an instrument used to measure the electric potential difference (voltage) between two points in an electrical circuit.
- Step 1: The primary requirement for a voltmeter is to draw minimal current from the circuit it is measuring to ensure accurate readings without altering the circuit conditions.
- Step 2: To achieve this, the voltmeter must have a high resistance. This high resistance is placed in series with a sensitive component called a galvanometer.
- Step 3: The galvanometer itself is a device that measures current, and by connecting it in series with high resistance, the current flowing through the galvanometer is kept minimal, resulting in a more accurate voltage reading.
