Consider the RC circuit in the figure below. The switch was at position a for a long period of time and is switched to position b at time t = 0. a) Suppose R=493Ω, C=4.4μF, and Vb=4.6 V. What will be the voltage drop across the resistor at t=1.7 ms? b) How much energy in total will eventually be dissipated by the resistor? c) Now suppose that the switch has been at position b for a long time and is switched to position a at t = 0 s. What will be the voltage drop across the capacitor after 1.7 ms?

Transcribed Image Text:The image depicts an electrical circuit diagram featuring a switch, resistor, capacitor, and a battery. Here's a detailed breakdown:
1. **Battery (Vb):**
- Positioned on the left side of the diagram, it's indicated with the symbol for a voltage source. The voltage across the battery is labeled \(V_b\).
2. **Switch (a and b):**
- Located between the battery and the rest of the circuit.
- The switch can toggle between two positions: open and closed (indicated by a dashed line and two labeled points "a" and "b"). The switch is currently shown connected at point "a," completing the circuit.
3. **Resistor (R):**
- Identified with a zigzag symbol, it is connected to the switch. The component is labeled with "R," representing resistance.
4. **Capacitor (C):**
- Shown with two parallel lines, the capacitor is connected to the resistor. It is labeled with a "C."
5. **Voltage across the Capacitor (Vc):**
- The voltage across the capacitor is marked as \(V_c\).
Overall, this configuration represents a simple RC charging circuit, where the capacitor can charge or discharge through the resistor depending on the position of the switch.
