### Understanding Equivalent Inductance in Series Circuits#### Problem StatementConsider the circuit below with \( i(t) = 80 \cos(50t) \, \text{mA} \) for \( t > 0 \) and \( i(t) = 0 \) for \( t < 0 \). Given the inductances \( L_1 = 60 \, \text{mH} \), \( L_2 = 20 \, \text{mH} \), and \( L_3 = 10 \, \text{mH} \):![Circuit Diagram](image_url_here)**Question 5:**What is the equivalent inductance? (Be sure to enter an answer here and show your calculations in detail on your paper for submission.)#### Circuit ExplanationThe circuit diagram consists of three inductors \( L_1 \), \( L_2 \), and \( L_3 \) connected in series with a current source \( i(t) \). When inductors are connected in series, the total or equivalent inductance \( L_{eq} \) is the sum of the individual inductances.---### Detailed SolutionWhen inductors are connected in series, the equivalent inductance \( L_{eq} \) is calculated using the formula:\[ L_{eq} = L_1 + L_2 + L_3 \]Given:- \( L_1 = 60 \, \text{mH} \)- \( L_2 = 20 \, \text{mH} \)- \( L_3 = 10 \, \text{mH} \)Substituting the values into the formula:\[ L_{eq} = 60 \, \text{mH} + 20 \, \text{mH} + 10 \, \text{mH} \]\[ L_{eq} = 90 \, \text{mH} \]Thus, the equivalent inductance \( L_{eq} \) of the circuit is \( 90 \, \text{mH} \).Please ensure you show your detailed steps in your calculations when submitting your paper.

The voltage drop across a capacitor with capacitance C is given by q(t)/C, where q is the charge on the capacitor. Hence, for the RC series circuit, Kirchhop's second law gives 2. 1 Ri + 79 E(t). But current i and charge q are related by i = dq/dt. So, the above equation becomes dą R- 1 E(t). dt T9 Use this differential equation to solve the following: (b) Let R = 10 ohms and C = 0.1 farad. Let E(t) be exponentially decaying, say, E(t) = 30e * volts. Assuming q(0) = 0, find and graph q(t). At what time does q(t) reach a maximum? What is that maximum charge? Ans: q(t) = 1.5(et -e-3t); q'(t) = 0 gives tm = 0.549; qm = 0.577 coulomb
