How do you determine the current if you know the wattage and the voltage?

Explanation:
To determine the current when you know the wattage and the voltage, you can apply Ohm's Law, which states that power (measured in watts) is equal to the voltage (measured in volts) multiplied by the current (measured in amperes). The relationship is expressed by the formula: Power (W) = Voltage (V) × Current (I) From this formula, you can rearrange the equation to find the current: Current (I) = Power (W) / Voltage (V) This shows that current is calculated by dividing the power in watts by the voltage in volts. Using this method allows you to accurately calculate how much current is flowing in the circuit based on the known values of wattage and voltage. This concept is fundamental in electrical training and is particularly important for ensuring that circuits operate safely and efficiently. Understanding these relationships is crucial for anyone working with electrical systems, especially in commercial food equipment service.
