There are two coils in watt meter namely current coil & potential coil.the two ends of current coil are 'M' & 'L' and they should connect in series with instrument. and the two ends of p.c. is 'c' which is connected to 'L'. and another is at the other end of instrument.There are two coils in watt meter namely current coil & potential coil.the two ends of current coil are 'M' & 'L' and they should connect in series with instrument. and the two ends of p.c. is 'c' which is connected to 'L'. and another is at the other end of instrument.There are two coils in watt meter namely current coil & potential coil.the two ends of current coil are 'M' & 'L' and they should connect in series with instrument. and the two ends of p.c. is 'c' which is connected to 'L'. and another is at the other end of instrument.

Does watt meter reading go negative?
Yes!
What is function of pressure coil in a watt meter?
A 'pressure coil' is an archaic term for a 'voltage coil' (UK terminology) or 'potential coil' (US terminology), as opposed to the 'current coil' in a wattmeter. This coil is connected in parallel with the supply, while the current coil is connected in series with the load.
Why is the electric watt meter connected in series with the rest of the circuits in the house?
First of all, you are referring to an energy meter, not a wattmeter. A wattmeter measures power, in watts, whereas an energy meter reads energy, in watt hours (or, more specifically, kilowatt hours). The energy company bills you for energy, not power.Having said that, the connections each instrument are the same. In fact, there are two coils inside an energy meter: a current coil, and a voltage (or potential) coil. The current coil is connected in series with the load while the voltage coil is connected in parallel with the supply voltage.The current coil measures the in-phase component of the current drawn by your load, so that the instrument always reads the true power (multiplied by time -the function of the aluminium disc) of the load -i.e. not the apparent power or reactive power.
How current coil is connected in energy meter?
It's connected in series with the load.
What is the difference between single phase and three phase voltage measurement?
Phasing, or the number of phases in an electrical system has nothing to do with the voltage. A single phase and three phase supply could have a voltage supply of any given voltage from virtually 0 to infinity. Most single phase power supplies in the US are 120/208-240 volt. Three phase power supplies are typically 120/208 to 277/480 volt.
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.
What is a Kill-a-Watt-meter?
Kill-a-Watt is a commercial product that measures the number of kilowatts of power you consume from the power line connected to it.One Kilowatt is 1000 watts.NoteYou don't consume power; you consume energy which is expressed in kilowatt hours, not kilowatts.
What are the types of electrodynamometer?
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
Does watt meter reading go negative?
Yes!
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.
What instrument measures watts?
A watt meter will measure watts.
What is function of pressure coil in a watt meter?
A 'pressure coil' is an archaic term for a 'voltage coil' (UK terminology) or 'potential coil' (US terminology), as opposed to the 'current coil' in a wattmeter. This coil is connected in parallel with the supply, while the current coil is connected in series with the load.
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.
