The Magic of a Simple Circuit

💡 A simple circuit is the foundation of electronics! It lets electricity flow and makes stuff happen

🔋 Battery: Think of it like a powerhouse storing energy waiting to be used.

🚧 Resistor: Slows down the flow of electricity, kind of like a speed bump for electrons. Keeps your components safe!

✨ LED: This little gadget turns electricity into light!

Let’s Build!

🔋➡️🚧 Connect the battery’s positive (+) end to one side of the resistor.

🚧➡️✨ Connect the other side of the resistor to the LED’s positive (+) leg.

✨➡️🔋 Connect the LED’s negative (-) leg to the battery’s negative (-) end.

BOOM! Your circuit is alive! 🎉 The LED should light up – proof your creation works.

Simple Series Circuit

A simple circuit with 2 resistors, 2 LEDs in series, a battery, and a switch is a basic electronic setup that allows electricity to flow through it.

Less current flows through series circuit so the intensity of LED is less.

🔋 A coin battery labeled “CR2032 3.0V” is the power source.

➕ The positive terminal of the battery is connected to a red wire.

🪛 A battery holder secures the coin battery.

🟢 The red wire leads to one end of a resistor.

🟤 The resistor is colored with stripes, indicating its resistance value.

🟢 Another green wire connects the other end of the first resistor to one leg of a red LED.

🔴 The red LED’s other leg connects to a second resistor, similar to the first.

🟢 A final green wire completes the circuit back to the minus terminal of the battery.

Construction and Working:

• 🔋 Power Source: The coin cell battery provides a 3.0-volt direct current supply.
• 🛠️ Resistors: Two resistors are included to limit the current flowing through the LEDs, preventing them from burning out.
• 💡 LEDs: Light Emitting Diodes (LEDs) light up when electric current passes through them.
• ➡️ Circuit Path: Electricity flows from the battery’s positive terminal, through the resistors, LEDs, and back to the negative terminal.
• 🌟 Illumination: When the circuit is complete, the LEDs emit light as the electric current flows through them.

🔧 This simple circuit likely serves as an illustrative example or a basic electronic project, demonstrating how LEDs can be powered using a coin cell battery with appropriate current limiting resistors to prevent damage to the LEDs.

Simple Parallel Circuit

🔋 A coin battery labeled “CR2032 3.0V” serves as the power source.

➕ The positive terminal of the battery connects to two separate circuits in parallel.

🪛 The battery is held in place by a battery holder.

🟢 A green wire leads from the positive terminal to the first circuit, consisting of a red LED.

🔴 The red LED is connected in series with a resistor.

🟤 The resistor has color bands, indicating its value, and limits the current through the LED.

🟢 Another green wire connects the first circuit back to the negative terminal of the battery, completing the circuit.

🟢 From the positive terminal, a second green wire leads to another parallel branch with a similar series combination of a red LED and a resistor.

🟤 The second resistor, identical to the first, ensures that the current through the second LED is also limited.

🟢 The second circuit is completed as the wire returns to the negative terminal of the battery.

Construction and Working:

🔋 Power Source: The CR2032 coin cell battery provides a stable 3.0-volt supply.

🔀 Parallel Circuits: Two parallel branches allow electrons to flow through two paths.

💡🛠️ LEDs and Resistors: Each branch contains an LED and a resistor in series to protect the LED by limiting the current.

🔄 Completing the Circuit: Wires complete the circuits by returning to the negative terminal of the battery.

🌟🔆 Illumination and Intensity: When the circuit is active, both LEDs illuminate. The parallel setup ensures that each LED receives enough current, potentially increasing their brightness compared to a single LED in a simple series circuit.

🔄🚦 Independent Operation: Because the LEDs are in parallel, they operate independently. If one LED were to fail, the other would continue to light up.

🔧 This parallel circuit demonstrates the basic principles of how electrical components like LEDs can be arranged to share a power source while operating independently, with each branch having its own current path which can increase the overall intensity of the LEDs compared to a series circuit.

More current flows through each branch of parallel circuit so the intensity of LED is more.
