Types of electrical circuits. There are three main types of circuits encountered in a domestic situation. They are ring circuits, radial circuits and lighting circuits.
An Integrated circuit is an association (or) connection of various electronic devices such as resistors, capacitors and transistors etched (or) fabricated to a semiconductor material such as silicon or germanium. It is also called as a chip or microchip. An IC can function as an amplifier, rectifier, oscillator, counter, timer and memory. ICs can be categorized into two types Analog or Linear integrated circuits (IC) and Digital integrated circuits (ICs).
