The current flowing in a coil is $3 \text{ A}$ and the power consumed is $108 \text{ W}$. If the a.c. source is of $120 \text{ V}, 50 \text{ Hz}$,the resistance in the circuit is (in $\Omega$)

The reactance of a $25\,\mu F$ capacitor at the ac frequency of $4000\, Hz$ is

The voltage across a pure inductor is represented by the following diagram. Which of the following diagrams will represent the current?

Consider a pure inductive $A$.$C$. circuit as shown in the figure. If the average power consumed is $P$, then

The equation of current in a purely inductive circuit is $i = 5 \sin (49 \pi t - 30^{\circ})$. If the inductance is $30 \, mH$,then the equation for the voltage across the inductor will be. (Let $\pi = \frac{22}{7}$)

The inductive reactance of an inductor of $\frac{1}{\pi } \, H$ at $50 \, Hz$ frequency is.....$\Omega$.
