At parallel resonance, the line current is ___________

Minimum
Maximum
Quite large
None of the above

The correct answer is: A. Minimum

At parallel resonance, the inductive reactance and capacitive reactance cancel each other out, leaving only the resistance in the circuit. This means that the current through the line is at its minimum value.

Option B is incorrect because the current through the line is at its minimum value, not its maximum value.

Option C is incorrect because the current through the line is not quite large, it is at its minimum value.

Option D is incorrect because the current through the line is not none of the above, it is at its minimum value.
