Given data:
- Induced voltage on open circuit (Eo) = 127 V
- Terminal voltage (Vt) = 120 V
- Field circuit resistance (Rf) = 15 Ohm
- Armature resistance (Ra) = 0.02 Ohm

Calculating the load current:
- The terminal voltage of a generator is given by the sum of the induced voltage and the voltage drop due to armature and field circuit resistances.
- The equation for terminal voltage (Vt) is: Vt = Eo - Ia * Ra - Ia * Rf
- Given values: 120 = 127 - Ia * 0.02 - Ia * 15
- Simplifying the equation: Ia = (127 - 120) / (0.02 + 15) = 7 / 15.02 ≈ 0.466 A
Therefore, the load current of the shunt generator is approximately 0.466 A.
