CUET and UG exam CUET UG 2025 Mock Test Series Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
When an AC source of emf \(\mathrm{e}=\mathrm{E}_{0}\sin(100\mathrm{t})\) is connected across a circuit, the phase difference between the emf \(\mathrm{e}\) and the current \(\mathrm{i}\) in the circuit is observed to be \(\pi/4\), as shown in the diagram. If the circuit consists possibly only of \(R-C\) or \(R-L\) or \(L-C\) in series, find the relationship between the two elements.
1
\(R=1\ k\Omega ,C=10\mu F\)
2
\(R=1\ k\Omega ,C=1\mu F\)
3
\(R=1\ k\Omega ,L=10 H\)
4
