What is voltmeter with circuit diagram?

Voltmeter which is also known as voltage meter is an instrument that measures the voltage or potential difference among two points of an electronic or electrical circuit. Usually, the voltmeter is used for Alternating Current (AC) circuits or Direct Current (DC) circuits.

Where is the voltmeter in a circuit diagram?

Voltmeters are always placed in parallel with the circuit element being analyzed, and positions 3 and 4 are equivalent because they are connected with wires (and potential is always the same anywhere in an ideal wire).

How is a voltmeter designed?

A voltmeter is placed in parallel with a circuit element to measure the voltage drop across it and must be designed to draw very little current from the circuit so that it does not appreciably change the circuit it is measuring. To accomplish this, a large resistor is placed in series with the galvanometer.

How is a voltmeter wired into a circuit?

So, a voltmeter is connected in parallel with a circuit and an ammeter is connected in series with a circuit to measure its voltage and current respectively.
