Wattmeters are not used for loads which are purely capacitive or inductive, because no watts are consumed and no energy is consumed by the customer.
But amps must still be supplied by the power company to supply the customer's capacitive or inductive load and the result is measured in volt-amps reactive (VAR), which can be registered on a meter called a reactive power meter.
The ratio of watts to volt-amps is called the power factor (a capacitive load has a power factor close to zero). Industrial customers with a poor power factor are penalised with higher tariffs and encouraged to improve their power factor.

What is a meter socket?
The electrical power that you use from the utility company has to be metered. This is done with a plug in watt meter. The meter socket is what holds the electrical watt meter. It is this meter that the meter reader reads to give you your monthly billing for the electricity that you used.
How many voltmeter and ammeter are in dc watt meter?
There is no volt meter or amp meter in a DC watt meter.
Why you reset the zero point on the watt meter?
So that the result that you find on the watt meter after resetting it will be accurate
What is the relation between Newton meter and watt?
1 Watt = 1 Joule / Second = 1 Newton-meter / Second.
What are the types of electrodynamometer?
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
What instrument measures electrical power?
The Ammeter XD
Does watt meter reading go negative?
Yes!
How much power is used by a 35w bulb with 12v supply vs 110v supply?
it also depends on what meter you have, is it a KWH METER or a AH METER. IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)
What instrument measures watts?
A watt meter will measure watts.
Is the amount of electricity used in your home measured in amps or kilowatt hours?
The meter on the side of your house is a watt meter. You are charged for the electricity that you use in kilowatt/hours. See related links below
If this month the meter read 2714 watt hour at 0.08 per watt what will Ralph bill this month?
Ralph who? Where does he live?
How you can find out that your single phase energy meter is not running fast?
You can test it by 1. Turn off all loads - check that the meter is not showing any usage. Most utility meters have a black spot on the running disc that can be seen by the user. That black spot should not be moving at all if you have turned off all loads. 2. READ the meter. 3. Now take a 100 watt bulb and insert it into one of your lamps, and turn it ON. 4. In 10 hours, you will have used 1 KWhr (1000 watt-hours). If your meter reads in units of 10 KWhr, this will take a long time (100 hours). In that case, use 10 bulbs, each 100 watts, in various lamps to get 10 KWhr in 10 hours. If you pay 15 cents per KWhr, this is going to cost you $1.50.
