DC (Direct Current) circuit theory is a fundamental concept in electrical engineering that focuses on circuits carrying a constant, unidirectional flow of electric charge. It plays a vital role in understanding and analyzing electronic devices and power distribution systems that use direct current. In DC circuits, voltage, current, resistance, and power relationships are governed by Ohm's law, which states that voltage is equal to the product of current and resistance (V = I * R). DC circuit theory forms the foundation for designing and troubleshooting circuits found in electronic devices, batteries, and automotive systems. It is crucial for engineers and technicians to grasp the principles of DC circuit theory to ensure the proper operation of electrical systems and devices that rely on direct current.
