A closed circuit consists of a source of constant emf \(E\) and a choke coil of inductance \(L\) connected in series. The active resistance of the whole circuit is equal to \(R\). It is in steady state. At the moment \(t=0\) the choke coil inductance was decreased abruptly 4 times. The current in the circuit as a function of time \(t\) is \(\frac{E}{R}\left[1+x e^{-4 t R / L}\right]\). Find out value of \(x\). 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
