According to Ohm's Law, what is the formula for calculating voltage?

The correct formula for calculating voltage according to Ohm's Law is expressed as E = I x R. In this formula:

• E represents voltage (in volts),

• I represents current (in amperes),

• R represents resistance (in ohms).

This relationship indicates that voltage is the product of the current flowing through a conductor and the resistance of that conductor. In practical terms, this means that for a given resistance, if you increase the current, the voltage will also increase correspondingly. Conversely, if the resistance increases while the current remains constant, the voltage will also increase. This fundamental relationship is crucial in electrical engineering and troubleshooting electrical circuits, as it helps linemen predict how changes in one variable (current or resistance) will affect voltage, ensuring that systems operate safely and efficiently.
