**Problem 7: Energy and Natural Response in Series Capacitors** **Circuit Diagram Explanation:** - Two capacitors, 20 nF and 30 nF, are connected in series with a resistor of 100 Ω. - Capacitor 1 has an initial voltage, \( V_1 = 45 \, \text{V} \). - Capacitor 2 has an initial voltage, \( V_2 = 15 \, \text{V} \). - A switch is included in the circuit, initially open. **Problem Statement:** The switch has been open for a long time before closing at \( t = 0 \). Determine the following: a) The initial energy in each capacitor. b) The current, \( i(t) \), as a function of time. c) The energy delivered to the resistor over the interval \( 0 \le t < \infty \). d) The final energy trapped in each capacitor at \( t = \infty \).
