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

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 $\Omega$)

What is capacitive reactance? Write its unit.

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 $\pi/4$ radian. If the frequency of $AC$ is $50\, Hz$,then the phase difference is equivalent to the time difference:

If a resistor of resistance $4 \Omega$,a capacitor of capacitive reactance $6 \Omega$ and an inductor of inductive reactance $9 \Omega$ are connected in series with an ac source,then the impedance of the circuit is (in $\Omega$)
