power = torque * rpm
emf produced by generator(E)=no. of turns in coil*rate of change of magnetic flux
to find the relation between emf generated and Field current .....
A generator produces alternating current.
Depending on the type of generator: Electricity in the form of direct current (DC) or alternating current (AC) is produced.
direct current
UK mains ac current is produced from a rotating 3 phase generator, rotating at 50 cycles per second (50 Hz)
the cosine of the angle between voltage and current of generator is called power factor (pf) of generator.
Power is energy that you can put to work, such as the electric current produced from a generator or engine.Fuel is a material with potential energy, it can be used to produce energy.
The process in which electric current is produced when a spinning shaft rotates magnets inside a generator is referred to as 'Direct Current'. It is not expected to work by the normal standard physics model however some people claim it is just.
Perspective. They are one and the same, but from the perspective of a load and a generator, the load takes current (sinks it), and a generator generates it (sources it).
inversly proportional
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).
