Electricity and circuits are fundamental to modern technology, powering everything from smartphones to industrial machines. A circuit consists of a closed loop of conductive material, such as copper, that allows electricity to flow. Key components of a circuit include resistors, capacitors, transistors, and diodes, each serving a specific function in controlling and directing electrical current.
Electricity itself is generated by the movement of electrons through conductors, and understanding how circuits manage this flow is essential for engineers and electricians. As technology continues to evolve, the design and efficiency of electrical circuits play a crucial role in the development of devices like computers, medical equipment, and renewable energy systems.
