Laws of Circuit Analysis
The Laws of Circuit Analysis are fundamental principles used to analyze electrical circuits. The two primary laws are Ohm's Law and Kirchhoff's Laws. Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor, expressed as V = I \times R .
Kirchhoff's Laws consist of two rules: Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL). KCL states that the total current entering a junction must equal the total current leaving it, while KVL states that the sum of the electrical potential differences (voltages) around any closed circuit loop must equal zero. These laws help engineers and technicians design and troubleshoot electrical systems effectively.
