Direct current electric circuit is energized by dc electricity source, such as battery connected by conductor wire through one or more source and electrical elements. In order to make application of dc electricity, we need a dc circuit.

## DC Circuit Theory

Direct current has unidirectional (one direction) electric charge flow. This type of current can be obtained from rectified alternating current source or dc source like battery. A dc source has many applications such as recharging battery for supplying various application such as electric system, motor, and many more. This circuit consists on constant value of electric voltage and electric current. The value themselves are not affected by time-changing variable.

In order to understand the dc circuit theory very well, make sure to read these below in order :

Make sure you have read what is electric circuit first to understand later material.

## Simple DC Circuit

A battery connected to a light bulb using conducting wire will be a simple flashlight circuit. The electric current flows from positive terminal to light bulb and flowing through back to negative terminal, making an endless loop. This basic principle will lead to various application of dc circuit.

## Analysis Method DC Circuit

After few years, electric circuit has been developed into many applications and types related to its function and purpose. Thus, we need to learn about analysis method of electrical circuit, especially dc circuit, such as :## Analysis Theorem DC Circuit

The analysis methods of dc circuit above may not suffiecient to analyze a complex circuit. Therefore, we need to learn about analysis theorem of dc circuit below :Untuk Bahasa Indonesia dan penjelasan yang sederhana baca Konsep Dasar Rangkaian Listrik
