What SI unit is used to express power?
the answer for the si unit of power is the watt or w
What is the function of electric meter?
The function of the electric meter is to inform the power company how much electricity you have used - so they know how much to charge you !AnswerWhat is colloquially known as an 'electric meter', or 'electricity meter', is correctly termed an energy meter. As the name implies, an energy meter is used to measure the amount of energy (not'electricity', which is not a quantity!) purchased from the electricity supply company for the purpose of billing its customers. This energy is measured in units called kilowatt hours (kW.h) and, for this reason, energy meters are sometimes referred to as 'kilowatt hour meters' or 'watt hour meters'.
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 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.
Which SI unit for energy is also called the newton-meter?
The newton metre is a unit of torque (or moment).
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 SI unit is used to express power?
the answer for the si unit of power is the watt or w
How many voltmeter and ammeter are in dc watt meter?
There is no volt meter or amp meter in a DC watt meter.
What is the name of an energy measure?
It depends on the type of energy:Foot-pound (torque)Newton-meter (torque)Joule (energy in general)Watt-second (electricity)Kilowatt-hour (electricity)BTU (heat)Calorie (heat)
How do you Calibrate energy meter with the help of wattmeter and stop watch?
A watt is one joule per second - a joule is the SI unit of energy.

What are terms for energy?
BTU, calorie, erg, foot pound, electron volt, watt hour, newton meter
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.
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 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 is the relation between Newton meter and watt?
1 Watt = 1 Joule / Second = 1 Newton-meter / Second.
