In a watt-meter there are four terminals:
M,L which are the current coils and
C,V which are called as pressure coils . .
To measure the current the measuring instrument should be placed in series with the load but in case of voltage, the instrument should be connected in parallel to the load . .
therefore M from the current coil and C from the pressure coil are can be short-circuited to measure the power of the given circuit.

What is the relation between Newton meter and watt?
1 Watt = 1 Joule / Second = 1 Newton-meter / Second.
Basic components of watt-hour meter instruments?
See...wiki.answers.com/Q/How_does_a_watt-hour_meter_work
What are the basic units of watt?
The Watt is the unit for power in the SI system, defined as 1 Joule per second. A Joule is the work done in moving 1 meter against a force of 1 Newton. If you are not familiar with the metric system, you may like to know that 1 kilowatt (1000 watts) is equal to 1.341 horsepower. In electrical work the Watt is (volts x amps), that is the same quantity as 1 Joule/sec, which makes it easy in the metric system to work with mechanical and electrical quantities at the same time.
What electrical unit was named in Watt's honor?
The Watt, which is defined as 1 Joule per second
What are Joules a combination of?
The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.The joule is the unit of energy in the International System of Units, also known as SI. It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule.For more information see the answer to the Related Question.
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 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.
Does watt meter reading go negative?
Yes!
What are the M L C V terminals of a watt meter?
The M terminal connects to the power supply. The L terminal connects to the load. The C terminal is shorted to the M terminal. The V terminal connects to the systems neutral.
How do you connect an single phase watt meter?
Answer for USA, Canada and countries running a 60 Hz supply service.The wires from the utility connection will be connected to the top terminals jaws of the meter base. The bottom of the meter base terminal jaws will be connected to the top of the first over current device. This will be the service distribution's disconnect switch. The neutral will pass through the meter base with no grounding connection and continue on to the distribution's neutral terminal point.
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 do you safely remove a watt meter when the meter socket is energized?
First, shut off all power to your house.
What are ML CV in watt meter?
main , load, common, voltage
What is the function of watt meter?
The wattmeter is an instrument to measure the electrical power.
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.
