The correct curve between inductive reactance (XL) and frequency (f) is

When the values of inductance and capacitance in an $$L-C$$ circuit are $$0.5\  H$$ and $$8\ \mu$$F respectively then current in the circuit is maximum. The angular frequency of alternating e.m.f. applied in the circuit will be

The inductive reactance of a coil is $$2500\ \Omega$$. On increasing its self-inductance three times, the new inductive reactance will be

The inductive reactance of a choke coil of $$\displaystyle 1/4 \pi\  mH$$ in an $$AC$$ circuit of $$50\  Hz,$$  will be

The correct curve between the resistance of a conductor (R) and frequency (f) is

The capacitive reactance at $$1600\  Hz$$  is  $$81\ \Omega$$. When the frequency is doubled then capacitive reactance will be

An $$R-C$$ circuit is as shown in the following diagram.The capacity reactance and impedance will be

An alternating voltage frequency $$\omega$$ is induced in electric circuit consisting of an inductance $$L$$ and capacitance $$C$$, connected in parallel. Then across the inductance coil the
