An Ac source \( \varepsilon=\varepsilon_{0}[\cos (100 \pi t)+\cos (500 \pi) t] \) is connected in series with a capacitor \( \& \) a resistor. The steady -state current in the circuit is found to be
\[
\left.i=i_{1} \cos \left[(100 \pi) t+\phi_{1}\right]+i_{2} \cos [(500 \pi)) t+\phi_{2}\right]
\]
(1) \( i_{1}i_{2} \)
(2) \( i_{1}=i_{2} \)
(3) \( i_{1}i_{2} \)
(4) the information is insufficient to find the relation \( b / w_{i}, i_{1} i_{2} \)
