Discuss the applicability of the final-value theorem for obtaining the value of i2(t) as t → ∞ for the circuit of Example 5.29.
Example 5.29
A voltage e(t) is applied to the primary circuit at time t = 0, and mutual induction M drives the current i2(t) in the secondary circuit of Figure 5.10. If, prior to closing the switch, the currents in both circuits are zero, determine the induced current i2(t) in the secondary circuit at time t when R1 = 4 Ω, R2 = 10 Ω, L1 = 2 H, L2 = 8 H, M = 2 H and e(t) = 28 sin 2t V.
