### Example #5: The RC Dis-Charging Circuit

The circuit shown is just Circuit B reused from Example #3:

\[V_{\text{bat}} = 12\,V, \ C = 100\,\mu F, \ \text{and} \ R_1 = R_2 = R_3 = R_4 = 25\,\Omega.\]

#### A. The instant after the switch has been re-opened (t = 0), DRAW THE DISCHARGING CIRCUIT in the space provided, and use it to determine the current flowing through each resistor.

**Circuit B:**

- This circuit is a series-parallel combination where four resistors (\( R_1, R_2, R_3, R_4 \)), a battery (\( V_{\text{bat}} \)), and a capacitor (\( C \)) are present.
- \( R_1 \) and \( R_2 \) are connected in series.
- \( R_3 \) and \( R_4 \) are connected individually in parallel to the series combination of \( R_1 \) and \( R_2 \).
- The capacitor (\( C \)) is in parallel with \( R_4 \).

**The DIS-Charging Circuit:**

- To explain the discharging circuit analytically:
  - When the switch is opened at \( t = 0 \), the capacitor \( C \) will start to discharge through the resistors.
  - As the switch is opened, the battery is disconnected, and the resistors will form a path for current via the charge stored in the capacitor.
  - Initially, the current through each resistor can be determined by analyzing the instantaneous discharge.
