Ever wondered how electricity really works? Ohm's Law is the fundamental principle that governs the relationship between voltage, current, and resistance in an electrical circuit. Simply put, it states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
Think of it like this: Voltage (V) is the 'push' that drives the current (I) through the circuit. Resistance (R) is like a 'squeeze', hindering the flow of current. Ohm's Law is expressed as: V = I * R.
Knowing Ohm's Law allows you to calculate any one of these values if you know the other two. For example, if you know the voltage and resistance, you can easily determine the current. It's essential for designing circuits, troubleshooting electrical problems, and understanding how electronic devices function. Understanding Ohm's Law provides a solid foundation for understanding electronics.
