Ohm’s Law and Power Equation are fundamental concepts in the field of electrical engineering and physics. These principles help us understand the relationship between voltage, current, resistance, and power in an electrical circuit. By applying these formulas, we can analyze and design various electrical systems with precision.
Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. The formula is expressed as I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
