What would happen if a shunt-excited DC generator was operated at too low a speed?

A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.


How the line representing the critical resistance of a DC generator just touches its characteristics?

The line representing the critical resistance of a DC generator is the maximum resistance at which the generator can operate while still delivering the rated voltage. This line just touches the generator's characteristic curve at the point where the terminal voltage drops to zero under no-load conditions. Beyond this critical resistance, the generator will fail to build up voltage, as the armature reaction and losses exceed the induced electromotive force (EMF). The critical resistance is crucial for determining the stability and performance of the generator under varying load conditions.


Which is usually produced by a generator ac or DC?

An ac generator produces ac, a dc generator produces dc, it all depends on the generator.

Why DC motors and DC generators are commonly known as DC machines?

because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.

What is critical resistance of the field circuit of a DC generator?

The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.

What are the possible reasons for failing the voltage of a dc shunt generator to build up during starting?

Possible reasons for failure of voltage buildup... 1) No residual Magnetism, 2) Field connection may be in reverse manner, 3) Field resistance is greater than critical resistance, 4) Speed is less than Critical speed.
