The ratio Φ 02 /Φ 01 ​ of the magnetic flux through a turn in inductor 2 to that in inductor 1 is 1.50. At time t = 0, the two switches are closed on B. At what time t is the flux through a turn in the two inductors equal?

and R and the potential differences across C and R: (a) at the instant after the switch is closed and ( b) long after it is closed. C In Figure (a) in Figure b switch S has been closed on A long enough to establish a steady current in the inductor of inductance L 1 = 5.00 mH and the resistor of resistance R 1 = 25.0 Ω .Similarly the emf across L The open switch in figure is thrown closed at t = 0 . before the switch is closed the capacitor is uncharged and all currents are zero . DEtermine the currents in L
