The study and application of electrical components and circuits is known as electronics. These "electronic components" regulate the flow of electricity for practical purposes.

Many electronic components can be found in electronic devices, like :

• resistors

• capacitors

• microcontroller

• connection wires

• circuit boards.

• coils of wire called inductors integrated circuits

• transformer

AC VS DC

In direct current, the voltage is always constant, and the electricity flows in a certain direction. In contrast, in alternating current, the voltage periodically changes from positive to negative and from negative to positive, and the direction of the current also periodically changes accordingly.
