Yes, most DMM are ''average responding", giving accurate rms reading if the ac voltage signal is a pure sine wave. They measure the average of the absolute value of ac voltage and are calibrated so that reading are corrected to that of the rms value of a sine wave.Error occur if harmonic are present.

What does a voltmeter measure voltage in?

A voltmeter measures voltage in volts.


What are the difference between a multimeter and a voltmeter?

A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, a multimeter combines a voltmeter, an ammeter, and an ohmmeter. The two main kinds of a multimeter are analog and digital. A voltmeter measures the potential difference (voltage) between two points. the voltmeter only measures volts.


How can you say that ammeter measures current and voltmeter measures voltage?

voltmeter in parallel and ammeter in series of a circuit.


Why is a voltmeter used rather than a potentiometer?

A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.


What does a Voltmeter do in a circuit?

A voltmeter measures the voltage present in the circut. Voltage is the amount of energy available to push charges through an electric circut.


What does voltmeter measures?

voltage in a circuit (also known as potential difference p.d.)A voltmeter or multimeter is an electrical instrument capable of measuring voltage, current, and resistance. Digital multimeters have numerical displays, like digital clocks, for indicating the quantity of voltage, current, or resistance. Analog multimeters indicate these quantities by means of a moving pointer over a printed scale.


How voltmeter works?

It is connected in parallel and measures potential difference.


Do barometer and voltmeter measure a wavelength?

A barometer measures atmospheric pressure. A voltmeter measures the difference in voltage between two points A wavelength has nothing to do with either of these measurements.


What intrusment measures voltage in a current?

A voltmeter. It's also one of the functions of a multimeter.


What instrument measures voltage?

Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.


What are the applications for a voltmeter?

The primary application of a digital DC voltmeter is to display the amount of DC current present in a circuit. This is particularly handy when troubleshooting problems.
