Question

**Title: Analyzing a Complex Electrical Circuit Using Kirchhoff's Rules**

**Introduction**

Consider the circuit shown in the diagram:

- It features a battery with an electromotive force (emf) $ \varepsilon = 20 \, \text{V} $ and an internal resistance $ r = 5 \, \Omega $.
- The resistors in the circuit are $ R_1 = 15 \, \Omega $, $ R_2 = 10 \, \Omega $, $ R_3 = 10 \, \Omega $, $ R_4 = 15 \, \Omega $, and $ R_5 = 5 \, \Omega $.

This circuit is noted as being surprisingly difficult and requires the use of Kirchhoff's rules for analysis.

**Objective**

a. Find the current through each resistor:
- Total current $ I_T $
- Current through each resistor $ I_{R1}, I_{R2}, I_{R3}, I_{R4}, I_{R5} $

b. Determine the power dissipated in the internal resistance $ r $ of the battery.

**Tasks**

1. **Calculation of Currents:**
- Use Kirchhoff's voltage and current laws to find the currents through each resistor.
- Fill the calculated values in the given placeholders for each corresponding resistor.

2. **Power Dissipation in Internal Resistance:**
- Calculate the power dissipated in the internal resistance $ r $ by using the formula:
\[
P = I^2 \cdot r
\]
- Find the current across $ r $ and use it to compute the power dissipation.
- Enter the calculated power in watts in the provided placeholder.

**Conclusion**

Apply Kirchhoff’s rules systematically to solve for unknown quantities in the circuit. This involves setting up equations based on loops in the circuit and the junction rule. Careful bookkeeping and solving of the resulting system of equations will yield the desired values.
