In a $$L C R$$ series circuit source voltage is $$120 \mathrm{~V}$$ and voltage in inductor $$50 \mathrm{~V}$$ and resistance is $$40 \mathrm{~V}$$, then determine voltage in the capacitor

In a series R-C circuit shown in figure, the applied voltage is 10 V and the voltage across capacitor is found to be 8V. Then, the voltage across R and the phase difference between current and the applied voltage will respectively be

An ideal coil of $$10 \mathrm{~H}$$ is connected in series with a resistance of $$5 \Omega$$ and a battery of $$5 \mathrm{~V}$$. After $$2 \mathrm{~s}$$, after the connection is made, the current flowing (in ampere) in the circuit is

In a circuit $$L, C$$ and $$R$$ are connected in series with an alternating voltage source of frequency $$f$$. The current leads the voltage by $$45^{\circ}$$. The value of $$C$$ is
