Answer: A

Share your understanding of this question with the correct explanation.

In a shunt generator, the field winding and the armature winding are connected in parallel. The load resistance is connected in series with the armature.

The generator emf can be determined using the formula:

Emf = Vt + Ia * Ra

Where:
Emf is the generator emf
Vt is the terminal voltage (output voltage)
Ia is the armature current
Ra is the armature resistance

Given:
Terminal voltage (Vt) = 200 V
Armature current (Ia) = 100 A
Armature resistance (Ra) = 0.01 ohms

Using the formula:

Emf = 200 V + (100 A * 0.01 ohms)
Emf = 200 V + 1 V
Emf = 201 V

Therefore, the generator emf is 201 V, which is connected in series with the load resistance.
