**Transcription and Explanation for Educational Use:** **Note:** For all problems, assume the switch has been in its initial position (at t < 0) for a long time. 1. **Find \( v \) for \( t > 0 \).** How much energy is stored in the capacitor at \( t = 0.1 \, s \)? - *Circuit Description:* - A 50 V voltage source is connected in series with a 50 Ω resistor and a switch. - When the switch is closed, the circuit connects to a parallel combination of a 20 Ω resistor and a 10 μF capacitor. 2. **Find \( v \) for \( t > 0 \).** - *Circuit Description:* - An ideal current source labeled \( i(t) = 4 \, A \) is connected in parallel with a 15 Ω resistor. - This parallel combination is then connected in series with a switch and a 10 Ω resistor. - When the switch is closed, it connects to a series combination of 22 Ω resistor and a 4 mH inductor. 3. **Find \( i \) for \( t > 0 \).** - *Circuit Description:* - A DC voltage source labeled 75 V is connected in series with a 20 Ω resistor and a switch. - When the switch is closed, it connects to a 30 Ω resistor in series with the 75 V battery. - Parallel to this combination is an 8 Ω resistor in series with a 1 H inductor. 4. **Find \( v(t) \) for \( t > 0 \) in the circuit below.** - *Circuit Description:* - A DC voltage source labeled 10 V is connected in series with a 5 kΩ resistor. - This is followed by a parallel combination consisting of a resistor and a circuit with: - A 15 V voltage source and a 100 kΩ resistor both in series with a switch. **Discussion of Components:** - The circuits involve resistors, capacitors, inductors, and both current and voltage sources. - Switches in the circuits imply that the condition changes at \( t = 0 \), necessitating analysis for \( t > 0 \). **Key Concepts:** - **Capacitors:** Store energy in the form of an
