The current in the primary coil of the transformer is approximately 174.24 A.
To calculate the current in the primary coil of the transformer, we can use the formula:
Current (primary) = Power (secondary) / Voltage (primary)
The power in the secondary coil can be calculated using the formula:
Power (secondary) = Voltage (secondary) × Current (secondary)
Given that the power station has an output of 33 kiloohms and a potential difference of 5 kV, we can calculate the current in the secondary coil:
Current (secondary) = Power (station) / Voltage (station)
= 33,000 ohms / 5,000 V
= 6.6 A
Now, let's calculate the power in the secondary coil:
Power (secondary) = Voltage (secondary) × Current (secondary)
= 132,000 V × 6.6 A
= 871,200 W
Finally, we can calculate the current in the primary coil using the formula mentioned earlier:
Current (primary) = Power (secondary) / Voltage (primary)
= 871,200 W / 5,000 V
= 174.24 A
Therefore, the current in the primary coil of the transformer is approximately 174.24 A.
