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.
the current coil is one through which the current of source can pass...pretty simple!!!....but the thing is that this coil is connected in series ....and voltage coil is connected parallel to the...
If I am not wrong then you have asked about a transformer. And its a current transformer. By theory of voltage transformer we know that Vs/Vp = Ns/NpSo for answering your question we need the value...
When the current in a nearby coil changes, the magnetic flux associated with it changes and an induced emf is produced in the other coil.Hence, induced current is produced.
In an analog induction type wattmeter the pressure coil is connected accross the voltage source.It is intentionally made to have a larger number of turns than the current coil so that it's impedence...
