Question
For the circuit below where \( C = 10 \mu F \), determine: A. \( V_c(0) \) B. \( V_c(\infty) \) C. \( V_c(t) \) for \( t \geq 0 \) D. \( i_C(t) \) for \( t \geq 0 \) ### Circuit Diagram Explanation: - **Components**: - A capacitor \( C \) with capacitance \( 10 \mu F \) is positioned in the middle of the circuit. - There are two resistors: one \( 20 \, \Omega \) resistor connected in series with a \( 10 \, mA \) current source on the left side, and another \( 40 \, \Omega \) resistor connected in series with a \( 20 \, mA \) current source on the right side. - **Switch**: - Initially at position 1, the switch changes to position 2 at \( t = 0 \). - **Current Sources**: - The left current source provides \( 10 \, mA \). - The right current source provides \( 20 \, mA \). - **Operation**: - The switch is closed at time \( t = 0 \), allowing the circuit to be analyzed in terms of transient and steady-state behavior. ### Analysis Tasks: - **\( V_c(0) \)**: Determine the initial voltage across the capacitor before the switch is moved. - **\( V_c(\infty) \)**: Determine the final, steady-state voltage across the capacitor long after the switch has been moved to position 2. - **\( V_c(t) \) for \( t \geq 0 \)**: Calculate how the voltage across the capacitor changes over time after \( t = 0 \). - **\( i_C(t) \) for \( t \geq 0 \)**: Determine the current through the capacitor as a function of time starting from \( t = 0 \).
