Mark the incorrect statement

In any AC circuit, the applied instantaneous voltage equals to the algebraic sum of the instantaneous voltages across the series elements of the circuit.

For circuits used for transporting electric power, a low power factor implies large power loss in transmission

Power factor can often be improved by the use of a capacitor of appropriate capacitance in the circuit

The use of a capacitor is avoided in the circuit of an induction coil
