Question

What is the potential difference $V_{a b}$ in Volts across the inductor $R_{1}$ ?

Open in App

Solution

At $t = 0$ , the current through inductor is $0$ .
Hence, the potential across $R_{1} = E = 120 V$
If there would be current through inductor then, there would be emf produced in the inductor and in that condition we have to treat the circuit as two cells in parallel one $E$ and other due to inductor .

Answer- $(120 V)$
