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.
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.
How is a watt meter connected?
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.
Why are electric meters connected in series with the rest of the circuits in the house?
Electric meters are connected in series with the rest of the circuits in the house because, that way, the meter can measure the current used by all of the circuits in the house. The meter integrates and records the current as power in kilowatt-hours.Another AnswerActually, energy meters are not simply 'connected in series' with the rest of the circuits in a house.In simple terms, an analogue energy meters contain twocoils: a current coil and a voltage coil. The current coil is, indeed, connected in series with the rest of the household circuits, but the voltage coil is connected in parallelbetween the line and neutral conductors. This means that the energy meter is monitoring the (in-phase) load current and the supply voltage, and the torque produced by the resulting magnetic fields is proportional to the power of the load.Power is a measure of the rate of energy consumption and, so, to determine the energy consumed by the load, the meter's combined magnetic fields drive a disc which, as it rotates, drives dials that record the amount of energy consumed over a given period (between meter readings). Energy (notpower!) is expressed in kilowatt hours (kWh).
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.

How do you connect energy meter in circuit?
pressure coil or voltage coil across the supply and the current coil in series.
What creep in energy meter?
The Aluminium disc in energy meter continues to slowly rotate even if no current is supplied to the current coil . This rotation of the disc is known as creep .

What is creep in energy meter?
In some energy meters, the disc rotates slowly and continuously when there is no load.the rotation of disc without any current through current coil and only due to excitation of pressure coil is called creeping.
What is current coil and voltage coil?
Oh, dude, current coils and voltage coils are just like the Beyoncé and Jay-Z of transformers. The current coil measures the current flowing through a circuit, while the voltage coil measures the voltage across a circuit. They're basically the dynamic duo of electrical measurements, keeping things in check and making sure everything runs smoothly.
How the current and pressure coils of the wattmeer are connected in circuit to measure the power drawn by load?
The current coil is connected in series with the load. The voltage coil (the term, 'pressure coil' is rather archaic!) is connected in parallel with the load. The wattmeter's polarity markings must be taken into account, or the meter will read downscale (backwards).

What could cause voltage in a coil that has no current running through it?
A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage <<>> Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
How an analog volt meter works?
The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
