If an $8\,\Omega$ resistance and $6\,\Omega$ reactance are present in an $ac$ series circuit,then the impedance of the circuit will be......$\Omega$.

Write the $SI$ unit of capacitive reactance.

The resistance of a coil for $DC$ is $5\,\Omega.$ In $AC,$ the resistance

What are phasors?

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

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:
