What is the formula for voltage?

The formula for voltage is represented by the equation V = I * R, where V stands for voltage (volts), I represents current (amperes), and R is the resistance (ohms). This relationship is derived from Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the circuit.

In practical terms, if you know the current flowing through a circuit and the resistance, you can easily calculate the voltage. This is fundamental in electrical engineering and circuit design because it helps in understanding how much electrical energy is needed to drive a specific amount of current through a given resistance. This formula is crucial for troubleshooting electrical systems and designing circuits that operate within safe limits.
