A wattmeter measures power, which is the rate of doing work, expressed in watts.

An energy meter measures the amount of energy consumed, usually in kilowatt hours.

The meter on the wall of your house is an energy meter.

How does watt and joule relate?

The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.


How do you adjust your home watt meter?

Your home doesn't have a wattmeter, it has an energy meter. And there are no adjustments you can make to it, as it is the property of the energy supply company.

What is the unit of electrical energy measured by an electric meter?

The international unit for energy is the joule, equal to the watt-second. Electric meters, however, are usually calibrated to measure kilowatt-hours (equal to 3.6 million watt-seconds).


What are the differences between a joule and a watt?

Joules versus wattsThe joule and the watt are closely related units. The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque.The watt is a unit of power and is defined as a joule per second, so you can see that power is work per unit time.One joule is equal to one watt-second.


How do you Calibrate energy meter with the help of wattmeter and stop watch?

How energymeter is used instead of wattmeter?

An energy meter measures power and time; a wattmeter measures an instantaneous value of power. Energy = Watt/seconds.


What Instrument measures electricity usage?

To measure electricity you use a multimeter to display voltage, resistance, amperage, etc. But to measure the rate at which you use electricity, I would recommend a Kill-A-Watt device, which tells you how much electricity appliances in your home are using, among other useful information.AnswerWhen you say 'electricity usage', you presumably mean 'energy consumption'? If this is the case, then you measure energy consumption using an energy meter which expresses energy consumption in kilowatt hours.
