The two batteries A and B, connected in given circuit, have equal e.m.f. E and internal resistance r1 and r2 respectively (r1 > r2). All the resistors have resistance R. Capacitor and Inductor have values of L an C respectively. The switch S is closed at t = 0. After a long time it was found that terminal potential difference across the battery A is zero. Find the value of R.
