Introduction

Electric and electronic circuits are two fundamental types of circuits that power our world. While electric circuits are responsible for large-scale power distribution and simpler applications, electronic circuits power more advanced digital technologies through miniaturized, low-power designs. Understanding the difference between these two types of circuits is crucial for fields like engineering and consumer technology.

Electric Circuit

An electric circuit is a closed loop that allows electric current to flow continuously. It consists of a power source (such as a battery or generator), conductive pathways (wires), and a load (a device that uses electric energy). Common examples of loads are light bulbs, motors, and heating elements.

• Power source: The power source provides the energy that drives the circuit. Common power sources include batteries, generators, and solar cells.
• Conductive pathways: Conductive pathways allow the electric current to flow through the circuit. Common conductive materials include copper and aluminium.
• Load: The load is the device that uses the electric energy from the circuit. Common loads include light bulbs, motors, and heating elements.

Functionality of Electric Circuits

Electric circuits are designed to deliver relatively high power over distances using thicker conductors and higher line voltages like 110/220V. They are used for simple tasks like controlling basic functions like lighting, and operating appliances and machinery.

Electronic Circuit

An electronic circuit is a type of circuit that uses active electronic components like transistors, diodes, resistors, and capacitors to process signals and perform logical functions. These components precisely control the flow of small electric currents to enable complex tasks like amplification, oscillation, and data processing.

Components of Electronic Circuits
