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.

How do you calculate armature current in a shunt generator?
To calculate the armature current in a shunt generator, you first need to determine the load current (I_load) and the shunt field current (I_shunt). The armature current (I_a) can then be calculated using the formula: ( I_a = I_{load} + I_{shunt} ). The shunt field current can be found using the field resistance and the terminal voltage. Once you have both currents, simply add them to find the total armature current.
How do you work out Armature current?
To calculate armature current in an electrical machine, you can use the formula: ( I_a = \frac{P_{out} + P_{loss}}{V_{a}} ), where ( I_a ) is the armature current, ( P_{out} ) is the output power, ( P_{loss} ) represents losses (like copper losses and iron losses), and ( V_{a} ) is the armature voltage. Alternatively, if you know the load resistance and applied voltage, you can use Ohm's Law: ( I_a = \frac{V_a}{R} ), where ( R ) is the load resistance. Ensure to account for any back EMF in your calculations for accurate results.
