List of top Physics Questions on Alternating current asked in AP EAMCET

An alternating current is given by \( i = (3 \sin \omega t + 4 \cos \omega t) \) A. The rms current will be:
A coil of inductance \(0.1\ \text{H}\) and resistance \(110\ \Omega\) is connected to a source of \(110\ \text{V}\) and \(350\ \text{Hz}\). The phase difference between the voltage maximum and the current maximum is
