TS EAMCET · Physics · Alternating Current
An alternating voltage \(\varepsilon=30 \sin 200 t\) (in volts) is applied to the circuit below. The amplitude of the current through the circuit is
- A \(3 \mathrm{~A}\)
- B \(2 \mathrm{~A}\)
- C \(1 \mathrm{~A}\)
- D \(0.5 \mathrm{~A}\)
Answer & Solution
Correct Answer
(A) \(3 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Given, applied emf is \(E=30 \sin 200 t\) In given circuit, \(L=0.05 \mathrm{H}, C=500 \mu \mathrm{F}\) \(R=10 \Omega, \omega=200 \mathrm{rad} \mathrm{s}^{-1}\) Now, inductive reactance, \(X_L=L \omega=0.05 \times 200\) \(=10 \Omega\) Also, capacitive reactance,…
