Question

How is a voltmeter connected in the circuit to measure the potential difference between two points?

Answer 1

Hint The voltmeter is the device or the instrument which is used to find the voltage of the circuit or the potential difference of the circuit. The voltmeter is used to determine the alternating current or direct current circuits. The radio frequency voltage is also measured by voltmeter.

Complete step by step solution
A galvanometer (current meter) that is delicate and is essential for a high opposition arrangement is the thing that makes a fundamental simple voltmeter. The meter ought to have a high inside obstruction. Else the circuit activity during the test would be hindered by drawing current fundamentally. The voltage range shown by the meter is dictated by the arrangement obstruction esteem and the galvanometer affectability.
Voltage is demonstrated legitimately in numeral structure by the advanced voltmeter. Voltage estimation as qualities up to certain critical levels could be dictated by a portion of these meters. From to volts are the greatest scopes of these functional lab voltmeters. Various scales that have power expands like , etc are produced as business voltmeters. To gauge low voltages, then again, an oscilloscope could be utilized where prompt voltage would be portrayed by the vertical removal. RF and AC applications have their top to top and top voltage estimated by the oscilloscopes. Wiring, protectors and uncompromising tests are vital for making the meters for estimating high expected contrasts.
So that the voltmeter is connected in parallel in the circuit to measure the potential difference.

Note The voltmeter is connected in the circuit in parallel to measure the voltage because if the voltmeter is connected in the parallel is to avoid the high amount of the resistance and to get the most accurate measurement of the potential difference.
