A Distribution transformer is supplied by a 2,400 volt primary line. The voltage ratio of this transformer from primary to secondary is 5:1. This unit delivers a secondary potential of___?

To determine the secondary voltage delivered by the distribution transformer, it is essential to understand how the voltage ratio works. The voltage ratio given is 5:1, indicating that for every five volts on the primary side, there is one volt on the secondary side.

With a primary voltage of 2,400 volts, the secondary voltage can be calculated using the ratio. Since the ratio is 5:1, you would divide the primary voltage by 5 to find the secondary voltage:

Secondary Voltage = Primary Voltage ÷ Voltage Ratio = 2,400V ÷ 5 = 480V.

This calculation clearly shows that the transformer delivers a secondary potential of 480 volts.

The other choices, while at various voltages, do not reflect the correct calculation based on the provided voltage ratio and primary voltage.
