What values are needed to find the maximum available output wattage of a power supply?

• A. Input voltage and input amperage
• B. Output voltage and output amperage
• C. Resistance and capacitance
• D. Voltage and temperature

Answer: (B)

To determine the maximum available output wattage of a power supply, the relevant values required are output voltage and output amperage. When calculating power, which is measured in watts, the formula used is: Power (W) = Voltage (V) × Current (A) In this context, the output voltage refers to the voltage that the power supply can deliver to the connected device, while the output amperage indicates the maximum current that the power supply can provide at that voltage. By multiplying these two values together, one can find the total wattage the power supply can output effectively to the load. Therefore, knowing both the output voltage and output amperage is crucial for understanding the limits of power delivery from the power supply. The other choices do not correctly correspond to the calculation of maximum output wattage for a power supply. Input values relate to what the power supply receives rather than what it can provide. Resistance and capacitance relate more to circuit behavior rather than direct power calculations, and voltage and temperature don't directly provide the necessary values to quantify power output.
