CUET and UG exam TS EAMCET Engineering Mock Test Series 2025 Physics Electromagnetic Oscillations and Alternating Current
A circuit connected to an ac source of emf \(e = e_0 \sin (100 t)\) with t in seconds, gives a phase difference of \(\dfrac{\pi}{4}\) between the emf e and current i. Which of the following circuits will exhibit this ?
1
RC circuit with \(R = 1 k \Omega\) and \(C = 1 \mu F\)
2
RL circuit with \(R = 1 k \Omega\) and \(L = 1 m H\)
3
RL circuit with \(R = 1 k \Omega\) and \(L = 10 mH\)
4
RC circuit with \(R = 1 k \Omega\) and \(C = 10 \mu F\)
