**Text Transcription for Educational Website:**

Refer to diagram 4.

Capacitor \( C = 5.98 \, \mu F \), resistor \( R = 18.3 \, \Omega \), and battery \( V = 4.32 \, V \) are connected in series to a switch that has been closed to position a for a long time. 

Now, the switch is suddenly thrown to position b. After time \( t = 0.821 \, ms \): find \( \frac{dI}{dt} \), the rate at which the current is changing in the circuit, in A/s. The sign of the answer will indicate if the current is increasing or decreasing.

**Diagram 4: RC Circuit**

This diagram represents a basic RC (Resistor-Capacitor) circuit. The components are connected in series with a DC voltage source.

**Components:**

- **V (Voltage Source):** Provides the electrical energy for the circuit.
- **R (Resistor):** Opposes the flow of current, dissipating electrical energy as heat.
- **C (Capacitor):** Stores electrical energy in an electric field, influencing the timing and behavior of the circuit.
- **Switch (a-b):** Controls the flow of current. In position 'a', the circuit charges the capacitor. In position 'b', the capacitor discharges through the resistor.

**Functionality:**

- When the switch is in position 'a', the circuit is closed and the capacitor begins to charge, opposing the voltage across it until fully charged.
- When the switch is moved to position 'b', the capacitor discharges, releasing the stored energy through the resistor. 

This circuit is commonly used in timing applications, filtering, and signal processing.
