4 **Title: Understanding Circuit Diagrams: Switch and LED Configuration****Educational Context:**In this exercise, we will explore a basic electrical circuit and understand the configuration and implications of its components. The circuit includes resistors, diodes, and switches, powered by a 5V power supply. **Circuit Diagram Explanation:****Components:**- **Power Supply Battery (PSB)**: Provides a 5V power source to the circuit.- **Resistors (R1, R2, R3, R4)**: - R1: 50 Ω (ohms) - R2: 50 Ω (ohms) - R3: 100 Ω (ohms) - R4: 100 Ω (ohms)- **Diodes (D1, D2)**: - D1: Blue LED - D2: Yellow LED- **Switches (SW1, SW2)**: **Circuit Layout:**1. The circuit starts at the PSB, with a 5V power supply.2. The current flows from the positive terminal through R1 (50 Ω resistor).3. It then flows to the junction where two parallel branches begin: - Branch 1: - Through D2 (Yellow LED). - Then through R4 (100 Ω resistor). - Branch 2: - Through R3 (100 Ω resistor). - Then through D1 (Blue LED).4. Both branches meet at a junction before continuing to R2 (50 Ω resistor).5. The flow then proceeds to SW2, back to the negative terminal of the power supply, completing the circuit.**Activity:**1. **Activate Switches**: Understand how closing (activating) SW1 and SW2 influences the flow of the circuit.2. **Observation**: Note the illumination of the diodes (D1 and D2) and the impact of different resistor values on the circuit's behavior.**Questions for Understanding:**1. **Question 2** - How do the resistors affect the brightness of the LEDs? - Discuss the potential differences across each component when both SW1 and SW2 are closed.**Diagram Interpretation:**- The circuit diagram shows a parallel configuration of LEDs with specific resistor values.- The two LEDs are in parallel but each has its series resistor to manage current flow.- **Understanding Circuit Behavior when SW1 is Closed**When examining the behavior of a circuit upon the closure of switch SW1, different scenarios can occur depending on the circuit's configuration. Below are potential outcomes you might experience:- **Option 1:** The potential at the junction between resistors R1 and R3 is pulled low, causing a potential difference across diode D2, which lights up yellow.- **Option 2:** The potential at the junction between resistor R2 and diode D1 is pulled low, causing a potential difference across D1, which lights up blue.- **Option 3:** The potential at the junction between resistor R2 and diode D1 is pulled high, causing a potential difference across diode D2, which lights up yellow.- **Option 4:** The potential at the junction between resistors R1 and R3 is pulled high, causing a potential difference across diode D1, which lights up blue.- **Option 5:** No observable effect, indicating that the circuit configuration may not be responding as expected or there could be an issue with the components.When analyzing circuits, it is important to consider the placement and configuration of components like resistors (R1, R2, R3) and diodes (D1, D2), as well as the behavior of potential differences and current flow when switches are activated. Understanding these can help diagnose why certain LEDs light up and others do not.For better comprehension, consider the following detailed descriptions:1. **Voltage Levels:** 'Pulled low' means the voltage at that point is reduced (close to 0V), while 'pulled high' means it is increased (closer to the supply voltage).2. **Potential Differences:** Creating a potential difference across a diode allows current to flow through it, causing it to emit light if it is a light-emitting diode (LED).3. **LED Colors:** Specific diodes (like D1 and D2) are mentioned to light up in different colors (yellow or blue), indicating the presence of specific LEDs designed for those colors.These principles are crucial for understanding and troubleshooting electronic circuits. Make sure to verify the actual wiring and component placement on your circuit to match expected outcomes.

What happens when SW1 is closed? O The potential at the junction between R1 and R3 is pulled low, causing a potential difference across D2, which lights up yellow. O The potential at the junction between R2 and D1 is pulled low, causing a potential difference across D1, which lights up blue. O The potential at the junction between R2 and D1 is pulled high, causing a potential difference across D2, which lights up yellow. O The potential at the junction between R1 and R3 is pulled high, causing a potential difference across D1, which lights up blue. O Mine did not do anything.
