🔍 Inside a Capacitor
Ever wondered what’s happening inside a capacitor?
It stores electrical energy and releases it when needed, which is why it’s so good at smoothing power supplies and filtering noise.

Here’s a quick look at how it charges and discharges.

A relay is an electrically controlled switch. When you send a small voltage to its coil, it creates a magnetic field that pulls an internal contact. That contact connects or disconnects another circuit. This lets you control high-voltage or high-current loads using a low-power signal from Arduino, sensors, or any small circuit.

In the GIF, you’ll usually see:

How does a servo actually work?
Inside every small RC servo, there’s a tiny DC motor, a set of gears, and a position sensor. The servo compares the incoming pulse (1 to 2 ms) with its internal position and moves the motor until both match. That’s why it always stops exactly at the angle you command. Fast, precise, and perfect for robotics

Do you know?
There’s a tiny component called a Crystal Oscillator inside your gadgets that keeps perfect time. It’s like a tiny heartbeat that makes sure your phone, computer, and microcontrollers never lose sync!

The Man Who Changed Modern Electronics: Mohamed Atalla

Do you know the person behind the invention that powers almost every modern device? His name is Mohamed Atalla, the engineer whose work led to the creation of the MOSFET.

He introduced the silicon surface passivation method that made stable MOSFETs possible. Today, billions of them are inside phones, laptops, microcontrollers and even the small circuits we build at home.
His contribution didn’t just improve electronics. It shaped the entire digital age.

Do you know? 🔋
There are different types of Li-ion batteries, and each one is made for a specific purpose:

NCR (NCA Chemistry)
Made for long backup time. These cells have very high capacity but are not meant for very high current.

INR (NMC Chemistry)
One of the safest and most balanced types. Good capacity, good safety, and can handle high current. Used in power tools and e-bikes.

ICR (LCO Chemistry)
High energy but lower safety. Usually used with protection circuits. Common in older devices and low-drain electronics.

IMR (LMO Chemistry)
Known for high safety and high discharge current. Slightly lower mAh but excellent for high-power devices like flashlights and tools.

Each battery type is made for a different job — capacity, safety, or high current. Always choose the right cell for your project!
