How do you calculate amps?

The correct method to calculate amperage (amps) is derived from the relationship defined by Ohm's Law, which correlates voltage (volts), current (amps), and power (watts). The formula used is amps equals watts divided by volts. This relationship can be understood by recognizing that power (in watts) is the product of current (in amps) and voltage (in volts).

When you rearrange the formula for power (P = V x I), you can isolate current by dividing both sides by voltage, leading to the formula for calculating amps:

Amps = Watts / Volts.

This formula is essential in various applications, as it allows you to determine how much current is being drawn by an electrical device when you know its power consumption and the voltage at which it operates. Understanding this calculation is crucial for ensuring circuits aren't overloaded and for the proper application of electrical devices in mechanical contexts.
