The formula "V = I × R" represents Ohm's Law, which describes the relationship between voltage, current, and resistance in an electrical circuit. Here, V stands for voltage measured in volts, I represents current measured in amperes, and R denotes resistance measured in ohms. This equation shows that voltage is equal to the product of current and resistance. In practical terms, if you know any two of these values, you can calculate the third. For example, increasing the resistance in a circuit while keeping the current constant will result in a higher voltage. Understanding this relationship is essential for designing and troubleshooting electrical systems.
