To determine the secondary transformer amps at full load, which formula is applied?

The formula used to determine the secondary transformer amps at full load is derived from the relationship between power (P), voltage (E), and current (I). The correct formula, P ÷ E = I, indicates that to find the current in amps, you would take the power in watts and divide it by the voltage in volts. This is based on the fundamental electrical equation where power is equal to voltage multiplied by current (P = E × I). Rearranging this equation to solve for current gives you the formula used here.

In practical terms, when you want to determine how much current a transformer will produce at full load based on its power rating and voltage, applying this formula allows you to calculate that current accurately. Knowing the voltage and the total power output of the transformer helps ensure that the system operates safely and efficiently without exceeding its designed current-carrying capability.
