Circuit Theory
Electric circuits are a network that comprises of a closed-loop, which helps in providing a return path for the current through a switch. When the switch is activated, the load operates, and the current accepts a path to finish the circuit at a low potential level from the opposing high potential level. Electric circuits theory is a linear analysis that helps in establishing a linear relation of voltage and current for R (resistance), L (inductance), and C (capacitance).
Question

Transcribed Image Text:**Problem Statement:**
2. Find \( v(t) \) for \( t \geq 0 \). Assume the switch has been open for a long time and is closed at \( t = 0 \).
**Circuit Diagram Description:**
The circuit consists of the following components:
- A 15 V voltage source connected in series with a 2 Ω resistor.
- A parallel branch includes:
- A 1/3 F capacitor with a voltage across it labeled as \( v \).
- A switch that is open for \( t < 0 \) and closes at \( t = 0 \).
- Another series branch contains:
- A 6 Ω resistor.
- A 7.5 V voltage source.
**Explanation:**
This question involves analyzing the transient response of a circuit when the switch closes at \( t = 0 \). The initial conditions are prior to closing the switch, where the system is assumed to have reached a steady state. Once the switch closes, the circuit dynamics will include evaluating how the capacitor voltage \( v(t) \) changes over time.
