: Store electrical charge temporarily and release it when needed; often used for filtering signals or smoothing power supply fluctuations.
Passive components are the fundamental building blocks of a circuit. They do not require an external power source to operate and can only store, dissipate, or release energy.
Transistors are the building blocks of modern electronics. They act as either switches or amplifiers. A small input signal can control a much larger current. basic electronics components and their functions pdf
Here are the most common passive components found in virtually every electronic circuit.
Takes a weak input signal (like an audio signal from a microphone) and boosts it into a much stronger output signal. : Store electrical charge temporarily and release it
A small toggle switch clicked under Mira’s finger. “Simple but essential,” said Arun. “Switches open and close circuits—like latches on doors controlling who may enter.” Mira liked the satisfying click that connected and disconnected a path.

They control a large current flowing between two terminals using a very small current or voltage applied to a third terminal.
Emit visible or infrared light when current passes through them.
Arun finished by placing a simple circuit board before Mira: a battery, a switch, a resistor, an LED, and a transistor. “Combine parts, and you can build anything,” he said.
