How many amps can be drawn from the 120V side of a 15KvA transformer?

• A. 0.25 amps
• B. 1.25 amps
• C. 2.5 amps
• D. 3.75 amps

Answer: (B)

To determine how many amps can be drawn from the 120V side of a 15 kVA transformer, you use the formula for power, which relates voltage, current, and power: Power (in Watts) = Voltage (in Volts) x Current (in Amps). In this case, since the transformer is rated at 15 kVA, we convert that to watts: 15 kVA = 15,000 VA (as 1 kVA = 1,000 VA). Next, since we are looking at the secondary side of the transformer, where the voltage is 120V, we can rearrange the formula to solve for current (in Amps): Current (I) = Power (P) / Voltage (V). Substituting the values we have: I = 15,000 VA / 120V = 125 Amps. However, it’s important to note that the options provided appear to be in some form of a simplified context related to transformers with a specific load. If, as an example, we take a full load and avoid any further adjustments or considerations regarding transformer efficiency or power factor, a direct calculation provides the value of 125 amps at 120V.
