What formula is used to calculate the kilowatts (KW) on a transformer?

The formula used to calculate the kilowatts (KW) on a transformer is based on the relationship between power (in watts), voltage (in volts), and current (in amps). The correct formula, which is Amps multiplied by Volts divided by 1000, effectively converts the result from watts to kilowatts.

This is because power in watts is calculated as the product of current (amperes) and voltage (volts). Since one kilowatt is equal to 1000 watts, dividing the product of amps and volts by 1000 converts the value from watts to kilowatts.

In practical terms, when you measure the current and voltage on the secondary side of a transformer and apply this formula, you obtain the total power output of the transformer in kilowatts, which is crucial for understanding its capacity and efficiency in delivering electrical energy.

This conversion is especially important in electrical applications where power ratings are often expressed in kilowatts rather than watts, hence utilizing this formula ensures accuracy and adherence to industry standards.
