What else can I help you with?
Is it true that ac voltmeter show r.m.s value?
yes it s true.
What does a voltmeter measure voltage in?
A voltmeter measures voltage in volts.
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
What are the effects on the voltmeter if voltages measured exceed the range?
If the voltage measured exceeds the voltmeter range then the voltmeter needle remains in it's maximum position until it's voltage values are considerably reduced.
Why is ideal resistance of a voltmeter infinity?
generally voltmeters are connected in parallel in the circuit.If the voltmeter resistance is lower as it increases the current rating,because by connecting parallel we are decreasing the resistance,so if the voltmeter resistance is not too much higher it leads to burning of the meter,For that we can conclude that the in ideal the voltmeter has infinite resistance.
Concept of ac voltmeter?
Red wire from a regular DC voltmeter should be connected to :
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
1 Which of the foll instrument can be used for both ac and dc?
voltmeter
What is used to monitor line voltage sag?
An AC voltmeter is ideal. If you really want to get fancy and analytic about it, you could use data-acquisition equipment to constantly read the AC voltmeter, and store or record the data.
Is it true that ac voltmeter show r.m.s value?
yes it s true.
How do you test a light bulb with a voltmeter?
To test a light bulb with a voltmeter, set the voltmeter to measure AC voltage. Then, place the voltmeter probes on the metal contacts at the base of the light bulb. If the light bulb is working properly, the voltmeter should display a voltage reading. If there is no reading, the light bulb may be defective and needs to be replaced.
What will happen if DC voltage is measured using AC voltmeter?
You will not get a measurement. depending on what kind of measuring device you use the socket could begin to smoke and the voltmeter will fly out (happened to me).
Will dc voltmeter measure ac voltage?
Oh, dude, let me break it down for you. So, like, a DC voltmeter is only gonna measure direct current voltage, ya know? If you try to use it on AC voltage, it's gonna be like trying to use a fork to eat soup - it's just not gonna work. So, yeah, stick to using an AC voltmeter for that job.
What is moving coil voltmeter?
mic or moving iron coil is instrument type works on ac and dc
Basic difference bet ac and dc?
If you measure the Instantaneous Volyage using a Voltmeter the1. DC the Voltmeter reading will remain constant it will not change.2. AC the voltage will vary from positive to negative . The variation can be sine wavw, Square wave, triangular wave or any other type.
Can a multimeter be used as substitute of ammeter and voltmeter why?
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!
Is Voltmeter Scale showing Volts with wavy line DC?
A voltmeter scale showing a wavy line typically indicates an alternating current (AC) voltage rather than direct current (DC). In AC measurements, the wavy line represents the sinusoidal nature of the voltage over time. If the voltmeter is intended to measure DC voltage, it should display a steady value without any fluctuations. Always check the voltmeter's settings to ensure it is used correctly for the type of current being measured.
