To solve the given circuit problem using the provided schematics and tables, we will follow these steps:

Steps to Analyze the Circuit:

1. Understand the Circuit Layout:

   • Identify all resistors $R_3, R_4, R_5$ and calculate their equivalent resistance in the parallel circuit if applicable.
   • Analyze the current flow and voltage based on the diagram and the source voltage $E_1 = 5 \, V$.

2. Complete Table 4.1:

   • Section 1 (Calculated Values):

     • $R_T$: Total resistance of the circuit.
     • $I_T$: Total current supplied by the source.
     • $I_{R3}, I_{R4}, I_{R5}$: Currents through individual resistors.
     • $P_T, P_{R3}, P_{R4}, P_{R5}$: Total power and power dissipated in each resistor.

   • Section 2 (Measured Values):

     • Use measured values to cross-verify the calculated values.

Key Calculations

1. Total Resistance $R_T$: Use the formula for resistances in parallel: $\frac{1}{R_T} = \frac{1}{R_3} + \frac{1}{R_4} + \frac{1}{R_5}$

2. Current through the Circuit $I_T$: Using Ohm's Law: $I_T = \frac{E_1}{R_T}$

3. Currents through Individual Resistors $I_{R3}, I_{R4}, I_{R5}$: For resistors in parallel, current division applies: I_{Rn} = \frac{E_1}{R_n} \quad \text{(for each resistor n = 3, 4, 5)}

4. Power Dissipation $P$: Power can be calculated using: $P = I^2 R \quad \text{or} \quad P = \frac{V^2}{R}$

5. Verify Results: Ensure the calculated total power matches the sum of powers dissipated in individual resistors.

Request for Further Information:

If you have specific values for resistors $R_3, R_4, R_5$, or if measurements are already available, share those details, and I will proceed with precise calculations and fill out the table.

Would you like detailed calculations and explanations for each step?

Follow-up Questions:

1. What are the values of resistors $R_3, R_4,$ and $R_5$?
2. Should I consider specific switch settings (e.g., $SA_1, SA_2$) for analysis?
3. Are you looking for calculated or experimental results first?
4. Should we discuss possible sources of error in measurements?
5. Would you like assistance in verifying experimental results?

Tip: Always cross-check calculated and measured values to ensure the consistency of results.
