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

Inductive reactance of a coil is expressed in

The phase difference between current and voltage in an $AC$ circuit is $\pi/4$ radian. If the frequency of $AC$ is $50\, Hz$,then the phase difference is equivalent to the time difference:

In an $A.C.$ circuit,the reactance of a coil is $\sqrt{3}$ times its resistance. The phase difference between the voltage across the coil and the current through the coil will be

What is the ratio of inductive reactance to capacitive reactance in an $AC$ circuit?
