In the circuit shown in the figure, the throw of the make-before-break switch has been at contact a for a long-time and the current in the 1.00 mH coil is equal to 2.20 A. At t = 0 the throw is rapidly moved to contact b. The total resistance R + rof the coil and the resistor is 11.0Ω. Discover the current when t = 0.500 ms.
