Question
The diagram illustrates a basic electrical circuit model featuring two rooms: a "Source room" and a "Sink room." 

### Components:

1. **Source Room**: 
    - Contains a figure labeled as 'A.'
    - Designated as the starting point of the electrical flow.
    - Connected to two wires, labeled as points 'A' and 'B.'

2. **Sink Room**: 
    - Contains a figure labeled as 'C.'
    - Designated as the endpoint of the electrical flow.
    - Connected to two wires, labeled as points 'C' and 'D.'

3. **Switch**: 
    - Positioned between the two rooms, controls the flow of electricity from the source to the sink.

4. **Batteries**: 
    - Represented outside the source room on the left, indicating the power source for the circuit.

5. **Wires**: 
    - Illustrated connecting the rooms, providing pathways for electrical current.

6. **Resistors**: 
    - Depicted outside the sink room on the right, showing components that impede the flow of electricity.

### Connections:

- **From Source to Sink**: 
    - Wire from point 'A' in the Source room runs through a switch to point 'C' in the Sink room.
    - Wire from point 'B' in the Source room runs directly to point 'D' in the Sink room.

### Purpose:

This diagram serves as a simplified representation of an electrical circuit, showing how electricity flows from a power source (batteries) through a switch and resistors, explaining concepts like current direction, circuit control, and resistance.

**Source Room Setup:**

- A 20V battery is connected to terminals A and B, with A being the point of higher potential. 
- The battery has an internal resistance of 0.25 ohms, which can be modeled as a resistor of 0.25 ohms in series with a perfect 20V source.

**Sink Room Setup:**

- A friend connects one resistor at a time to take measurements. The sequence of resistors used in the sink room are:
  1. 100 ohms
  2. 10 ohms
  3. 1 ohm
  4. 0.1 ohm

- Both you and the friend perform measurements for each resistor.

**Questions:**

a) What do you and your friend observe with the measurements?

b) What is the circuit like in the other room, and why?
