    always zero
  • b)
    1/3 of negative sequence current.
  • c)
    equal to negative sequence current
  • d)
    3 times negative sequence current
Correct answer is option 'C'. Can you explain this answer?

The positive sequence current of a transmission line is :a)always zero...
**Explanation:**

The positive sequence current of a transmission line refers to the current that flows in all three phases of the line in the same direction and with the same magnitude.

- The positive sequence current is **not always zero**. In fact, it is the **fundamental component** of the current waveform and is always present in a balanced three-phase system.

- The positive sequence current is **not 1/3 of the negative sequence current**. The negative sequence current refers to the current that flows in all three phases of the line in the opposite direction to the positive sequence current. The negative sequence current is generally smaller in magnitude compared to the positive sequence current.

- The positive sequence current is **not 3 times the negative sequence current**. This statement is incorrect and does not reflect the relationship between the two currents.

- The correct answer is **option 'C' - the positive sequence current is equal to the negative sequence current**. In a balanced three-phase system, the positive and negative sequence currents have the same magnitude but flow in opposite directions.

**In summary:**
- Positive sequence current: flows in all three phases in the same direction and has the same magnitude.
- Negative sequence current: flows in all three phases in the opposite direction to the positive sequence current and has the same magnitude.
- The positive sequence current is equal to the negative sequence current in a balanced three-phase system.
