Given data:
- Battery voltage (Vb) = 240 V
- Source voltage (Vs) = 230 V
- Current limiting resistance (Rs) = 8 Ω

Calculating the average battery charge current:
- The RMS value of the source voltage, Vs = 230 V
- The peak value of the source voltage, Vp = √2 * Vs = √2 * 230 ≈ 325 V
- The peak value of the rectified voltage across the battery, Vdc = Vp - 1.4 = 325 - 1.4 = 323.6 V
- The average value of the rectified voltage, Vavg = Vdc / π ≈ 103 V
- The average battery charge current, I = Vavg / (R + Rs) = 103 / (8 + 8) ≈ 8.82 A

Therefore, the average battery charge current is approximately 8.82 A. Option 'C' is the correct answer.
