What are the Main Differences Between Active and Passive Components in Electronics?

Active and passive elements are integral components in the electronics area. They help in the development and moving of various devices. These elements are incorporated into the electronic component’s settings and assist them in operating with utmost accuracy and precision. These devices are a fundamental part of electronic devices, but they vary from each other to a great extent. Here are a few notable benefits of active and passive components in electronics-

Based on external sources:

Active components are the ones that require a stable external source to function in a connection or circuit. Passive components are the ones that need a reliable external source to work in a connection or circuit.

Examples of Active and Passive components:

Diode, SCR, Transistor, ICs, Direct Current generator, and Current & Voltage devices are the leading equipment that uses active components. Resistors, Motors, Capacitors, Transformers, and Inductors are typical devices that work on Passive components.

Let’s understand about active or passive elements with examples-

SCR or Silicon Controlled Rectifier is an active element. When SCR is provided with current solely, it does not start working. It begins its operation when connected to a proper voltage source.

A capacitor is one of the most used passive components. Whenever a capacitor is connected to a stable electric current source, it starts working immediately. It does not require any voltage or external source to begin working.

Based on production and storage of power:

Active elements are the one that creates energy in the form of either voltage or current. Passive elements work by saving energy. These elements have power either as voltage or current.

Management of current:

Active components have the credible powers to control and administer the current flow. They can modify the movement of current in devices with utmost precision. Passive components do not have the power to alter the movement of current. They have to work with the provided current flow only.

Amplification power:

Active components are pretty robust in the amplification of signals. Passive components are not capable of boosting or amplifying the signals. Active components win when it comes to the provision of power gain.

Based on energy composition:

Active components act as the energy donors in the equipment. Passive components work by being the energy contributors to the connections. Active components are classified in the linear category, whereas passive ones are put in the non-linear range. Linearity in active and passive components is described according to Ohm’s law. Linearity is described when the voltage drop in the device remains linear to the resistance offered in the device. Non-linearity refers to the electronic devices in which output signal strength does not fall in direct proportionality to input signal strength.
