railway RRB JE (CBT I + CBT II) Mock Test 2024 Network Theory Transient Analysis Step Response of First Order Circuits
For a circuit given in the figure, switch K is closed to position 1 at t = 0. After t = 1 TC (Time Constant), the switch is moved to position 2. Find The Current I at 1TC(-) (just before one-time constant time) and 1TC(+) (just after one-time constant time) respectively (assume 1/ e ≃ 0.37)
