The phasor diagram of a load represents which circuit?

Three solenoid coils of same dimensions, same number of turns and same number of layers of windings are taken. Coil 1 has inductance L₁ wounded by Mn wire of resistance 6 $$\Omega$$m^$$-$$1, coil 2 with inductance L₂ wounded by similar wire but in reverse direction in each layer. Coil 3 with inductance L₃ wounded by a superconducting wire. The relation between their self inductances will be

In the circuit shown in figure, the AC source has angular frequency $$\omega$$ = 2000 rad s^$$-$$1. The amplitude of the current will be nearest to
