What is the maximum amp delivery of a 25 KVA transformer with 120/240 volts secondary windings when connected to a 240-volt load?

To determine the maximum amp delivery of a 25 KVA transformer with secondary windings rated for 120/240 volts when connected to a 240-volt load, we first need to convert KVA to amps using the formula:

Amps = KVA × 1000 / Volts

In this case, the transformer is rated at 25 KVA, and the load is connected to the 240-volt secondary. Therefore, we use:

Amps = 25 KVA × 1000 / 240 volts

Calculating that gives:

Amps = 25000 / 240

Amps ≈ 104.17

This means that the maximum current the transformer can safely supply at the 240-volt load is approximately 104 amps. Thus, the correct answer reflects this calculated value, which indicates how much current can flow through the secondary windings of the transformer when fully loaded. The analysis focuses on the relationship between voltage, power (in KVA), and current to ensure a proper understanding of transformer capacity in electrical circuits.
