Top 10 Electronic and Electrical Circuit Elements You Cannot Do Without

These circuit elements are the most basic parts of any electronic device.

The Top Ten

  1. Inductor

  2. Capacitor

    A capacitor is yet another simple but ingenious electrical circuit element, used in almost every electronic and electrical device you can find.

    So what does a capacitor look like? Actually, it comes in various shapes, but the most common one used is the cylindrical capacitor. A capacitor traps electrical energy in the form of an electric field in the space between two conducting metallic plates. The space is generally filled with a material of high dielectric constant to increase its capacitance, that is, to improve its performance and ability.

    A capacitor collects charge when current flows through a circuit and stores it. It's like a bank, which stores charge instead of money, slowly and gradually, to release it when needed.

    It is used for the start-up of many appliances like fans and in almost every electronic gadget we use today, like computers.

  3. Transistor

    Transistors brought a revolution to the electronic industry when they first came out. Earlier, triode valves used to do the jobs that today's transistors do. Because of that, computers made then were as big as today's city blocks. But transistors changed all of that when they first came out.

    All the logic operations done by our electronic devices are the result of the vast computing done by the IC. But the transistor is what led to the development of the IC. Transistors are used in signal amplification, as a switch, and in wireless communication systems.

    Transistors are amazing things. Simple but amazing.

  4. Semiconductor Diode

    It is often used as a rectifier for alternating current signals, in both half-wave rectification and full-wave rectification. It is also used as a photodiode, as a Zener diode for tackling a power source with an erratic voltage supply, in solar cells, and in LEDs.

  5. Fuse

    Safety is important, of course!

    Without this, an explosion is sure! Cool list, Ksunu!

  6. ADC (Analog-to-Digital Converter)

  7. DAC (Digital-to-Analog Converter)

  8. Crystal Oscillator

    Thank this for your working watches!

  9. Transformer

  10. Transducer

    Piezo transducers and LDRs are some examples.
