An RL circuit is shown on the right. L = 2.8 H. R=3722. = 9.5 V. L Voowooo (a) At moment t = 0.close the switch. Express the current I in the circuit as a function of time in terms of L. R. and e. (b) Express the inductive time constant. 7, in terms of L and R. (c) Calculate the numerical value of t. (d) Calculate the numerical value of I at t= 1 s in A. (e) Express the time to, when the current reaches one half of its maximum value, in terms of L and R. (f) Calculate the numerical value of to in s. (g) What's the direction of the current, clockwise or counterclockwise? (h) Express the magnitude of the induced emf on the inductor, el, in terms of L and I. 1) Express &z as a function of time in terms of e, L, and R. (Calculate the numerical value of ej at t= 0.01 s in V. (k) What's the direction of the induced current I1, counterclockwise or clockwise?
