What is voltmeter?
A voltmeter is a measuring instrument that is used in the measurement of the electric potential in volts.
What is the function of voltmeter?
for measurement of potential between two points.It is connected in parellal with the two points.
What is the procedure for measurement of true RMS Voltage?
In a non-reactive ckt, a simple measurement with an AC voltmeter is all that is needed. In a reactive ckt, you must first address power factor, which can be metered also, and combined with the apparent voltage as above to calculate true rms.
What is a word for a used to measure the power required to operate a device?
voltmeter
A DC wattmeter essentially consist of?
power i.e current and voltage or ammeter and voltmeter
Resistance and power measurement by voltmeter-ammeter method?
single phase power measure by three ammeter method
What is voltmeter?
A voltmeter is a measuring instrument that is used in the measurement of the electric potential in volts.
How do you measure the power by 3 voltmeter method?
first we connect the 3 volt meter in three loads then we measure the voltage and find the resistance of the loads then put the formula p=v/r so in this method we get the power by using 3 volt meter ....(prashant)

What is the method of making a rough measurement?
A method of making a rough measurement is: Estimation Answered by :PopTy13
What range should the voltmeter be set prior to taking a voltage measurement?
If the voltage is completely unknown, a voltmeter should be set to the maximum range first, then stepped down to an accurate level.
What is the importance of a voltmeter to a technician?
When a technician uses a voltmeter he or she can measure the power going through a circuit. It can test the safety and reliability of a an appliance also.Another AnswerA voltmeter is used to measure the potential difference, or voltage, between conductors. To measure power (as mentioned in the original answer) you need a wattmeter, not a voltmeter.
What are the disadvantages of using ammeter and voltmeter?
The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
What is the least count of a voltmeter?
The least count of a voltmeter is the smallest measurable change in voltage that the device can detect. It is determined by the resolution of the display and the sensitivity of the measuring components. It is important for accurate voltage measurement.
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
What is the ideal voltmeter high or low?
Ideal Voltmeter has an infinite resistance so it won't draw current from the circuit, but in real life ideal voltmeter doesn't exist.
