What is the relationship between voltage, current, and resistance described by Ohm's Law?

Ohm's Law is a fundamental principle in electrical engineering that defines the relationship between voltage, current, and resistance in a circuit. According to this law, the voltage across a conductor is directly proportional to the current flowing through it and is also related to the resistance of the conductor. This relationship is mathematically expressed as:

Voltage = Current x Resistance.

In this formula, voltage (measured in volts) is equal to the amount of current (measured in amperes) multiplied by the resistance (measured in ohms). This means if you know any two of these values (voltage, current, or resistance), you can calculate the third.

Understanding this relationship helps in designing and analyzing electrical circuits. If the resistance in a circuit remains constant, increasing the voltage will result in a corresponding increase in current, and vice versa. This principle is essential for troubleshooting and understanding how electrical devices function.
