What is Ohm’s Law?
Ohm’s Law is a fundamental principle in electrical engineering that states the relationship between voltage (V), current (I), and resistance (R):
V = I × R
This means that voltage is equal to the product of current and resistance. Additionally, power (P) can be calculated using the formula:
P = V × I
