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

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?

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:

Write the $SI$ unit of capacitive reactance.

In a series $LCR$ circuit,resistance $R = 10 \Omega$ and the impedance $Z = 20 \Omega$. The phase difference between the current and the voltage is.......$^o$

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