Inductive reactance of a coil is expressed in

The resistance of a coil for $dc$ is $R$ ohms. In $ac$, the effective resistance of the coil:

The impedance of a coaxial cable,when its inductance is $0.40 \mu H$ and capacitance is $1 \times 10^{-11} F$,is given by: (in $\Omega$)

The reciprocal of the total effective resistance of an $LCR$ $a.c.$ circuit is called:

The instantaneous values of current and voltage in an $AC$ circuit are $i = 100 \sin(314t) \ A$ and $e = 200 \sin(314t + \pi/3) \ V$ respectively. If the resistance is $1 \ \Omega$,then the reactance of the circuit will be:

The phase difference between current and voltage in an $AC$ circuit is $\pi/4$. If the frequency is $50\, Hz$,what is the time difference?
