Type test:
It is conducted on first prototype of product to confirm
the design specifications.This test is not repeated on
other products of same type.e.g, temp rise test
Routine test:
It is conducted on each product manufactured to confirm
proper maufacturing of each and every units.This test is
essential to be performed on each unit before distaching
the product to site.
a motor Will do work by consuming power a generator is just the opposite
The opposition to AC current flow in a circuit due to induction is called inductive reactance.The process of generating electrical current in a conductor by placing the conductor in a changing magnetic field is induction or just induction.
emf is electromotive force mmf is magnetic motive force emf drives electon where as mmf drives magnetic field
I think that he worked in the field of electrical engineering I hope this helps
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
voltage
The electrical field E = - dV/dr, the derivative of the electrical potential, V.
The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses.
In the time that an electronic field was invented by Thomas Edison in 1883, electrical devices already exist 100 years ago. The difference between this to devices depends how it manipulates electricity in the field of work, electrical take the electric energy then transform it in the form of heat, light or motion while the electronics are designed to manipulate the electrical current and it also is doing so much more.
What is the relationship between electrical frequency and magnetic field speed for an ac machine
Electromagnets only have a magnetic field when electrical current if flowing through them. When the power if off, so is the magnetic field. A bar magnet ALWAYS has a magnetic field.
differentiate between field experiment and survey and advantages
whats the difference in temperament between field springer spanialels and show.
The terminology E.M.F is the voltage output of a power source e.g a transformer bank, generator. As relates to potential difference it's a linear electrical field strenght between 2 points. E.g the charged plates of a capacitor.
If you mean an electric field it is the field that surrounds an electric charge. If you have two parallel plates with positive and negative charges, the amount of electric field in the space between the plates is the voltage difference divided by the distance. Electric field E is measured in volts per metre.

A measure of ability of a material tro resist the formation of electrical field within it equal to ratio between electrical flux density and electrical field strength generated by an electrical charge on the material. It is defined by permittivity.
