low power factor of an AC circuit means that It draws more reactive powerIt draws less line current  It causes less voltage drop in lineIt draws more active power

The power factor of an AC circuit is a measure of how effectively the circuit uses the power supplied to it. A low power factor indicates that the circuit is not using the power efficiently. Here's what each statement means:

1. "It draws more reactive power": Reactive power is the power that oscillates back and forth in the circuit, not doing any useful work. A low power factor means the circuit is drawing more reactive power, which is not efficient.

2. "It draws less line current": This statement is incorrect. A low power factor actually means the circuit draws more current for the same amount of useful power (active power). This can cause the power lines to heat up and potentially damage the circuit.

3. "It causes less voltage drop in line": This statement is also incorrect. A low power factor can cause a higher voltage drop in the line because more current is flowing through the line.

4. "It draws more active power": This statement is incorrect. The active power (the power that does useful work) is not affected by the power factor. A low power factor means the circuit is drawing more reactive power, not active power.
