**Diagram Explanation: Electric Circuit Analogy Using Rooms**

This diagram illustrates an analogy of an electric circuit using two rooms named the "Source room" and the "Sink room."

1. **Source Room:**
   - The source room is shaded in light beige.
   - It contains two individuals labeled at points A and B.
   - Three icons representing "batteries" indicate the presence of a power source.
   - Two wires lead out from the Source room, connected at points A and B.

2. **Sink Room:**
   - The sink room is shaded in light blue.
   - It contains two individuals labeled at points C and D.
   - Symbols representing "resistors" suggest the presence of resistance in this room.
   - Two wires enter the Sink room, connected at points C and D.

3. **Connections:**
   - A "switch" connects the wires coming from the Source room to the Sink room.
   - When the switch is closed, it allows the flow of electric current between the two rooms.
   - The wires symbolize the flow of electrons or the electric current between the Source and Sink rooms.

This analogy helps in understanding basic electric circuits, where:
- The Source room represents the power supply section.
- The Sink room represents the load section with resistors.
- Wires connect the components, and the switch controls the circuit flow.

### Electrical Circuit Experiment: Series and Parallel Resistors

**Setup:**

1. **Location:**
   - The experiment involves two rooms: the "Source room" and the "Sink room."
   
2. **Components:**
   - In the Sink room, resistors are connected: one 10-ohm resistor in series with two other 10-ohm resistors in parallel.
   
3. **Measurement:**
   - A measurement of 2 Amperes is taken going from point C to point D in the Sink room.

**Diagram Explanation:**

- The diagram shows two rooms labeled as "Source room" and "Sink room." 
- In the Source room, points A and B are connected with a wire leading to a switch.
- The switch connects to point C in the Sink room.
- In the Sink room, point C connects to resistors (arranged as described) and ends at point D, with an individual (E) standing nearby.

**Questions:**

a) **What do you and the friend see (with the measurements)?**
   - The measurement indicates a current of 2A flowing between points C to D in the Sink room.

b) **What is the circuit like in the other room? Why?**
   - With a 10-ohm resistor in series with two parallel 10-ohm resistors, the equivalent resistance is reduced due to the parallel combination. 
   - The series connection adds total resistance, affecting the current according to Ohm's Law.

**Key Concepts:**

- **Series Connection:** Adds resistance directly. The total resistance is the sum of individual resistances.
  
- **Parallel Connection:** Reduces total resistance. The inverse of the total resistance is the sum of the inverses of each individual resistance.

This experiment helps illustrate the behavior of current and resistance in series and parallel circuits.
