What is the formula for armature resistance of shunt excited DC generator?
The armature resistance of a shunt excited DC generator is calculated using the formula ( R_a = \frac{V - E}{I_a} ), where ( R_a ) is the armature resistance, ( V ) is the terminal voltage, ( E ) is the generated EMF (electromotive force), and ( I_a ) is the armature current. The difference between the terminal voltage and the generated EMF accounts for the voltage drop across the armature resistance due to the current flowing through it.
A 100KVA DC GENERATOR HAS ARMATURE RESISTANCE 0.02 OHMS AND A SERIES FIELD RESISTANCE 0.004 OHMS WHAT IS THE ARMATURE GENETATED VOLTAGE?
There is not enough information to answer the question. A DC generator is never described in kVA because DC generators are specified in terms of kilowatts.
Can you use the separately excited shunt generator machine as self excited generator?
You have a seperately excited generator and then you have a shunt generator which has the field winding in parallel with the armature terminals. In DC machines a separately excited generator could be run as a shunt generator provided the field winding is designed to work on the generated voltage. A separately excited alternator needs a DC supply for the field winding. In car alternators that is taken from the main winding via a rectifier and a voltage regulator.
What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
How can the direction of rotation of a DC shunt motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
What is the formula for armature resistance of shunt excited DC generator?
The armature resistance of a shunt excited DC generator is calculated using the formula ( R_a = \frac{V - E}{I_a} ), where ( R_a ) is the armature resistance, ( V ) is the terminal voltage, ( E ) is the generated EMF (electromotive force), and ( I_a ) is the armature current. The difference between the terminal voltage and the generated EMF accounts for the voltage drop across the armature resistance due to the current flowing through it.
What is the difference between a seperately excited DC generator and DC shunt generator?
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.
What is a shunt generator?
A shunt generator is a method of generating electricity in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.A direct current (DC) generator, not using a permanent magnet, requires a DC field current. The field may be separately excited by a source of DC, or may be connected to the armature of the generator so that the generator also provides the energy required for the field current.
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 is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
Is 4 point starter used to start and control the speed of dc shunt motor with armature resistance control?
yes
Theory for load test on dc shunt generator?
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.

What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
What is a shunted motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
