How many actual amps does a 5k Fresnel pull?

• A. 25A
• B. 41.5A
• C. 50A
• D. 60A

Answer: (B)

Current drawn by a load is power divided by voltage. A 5,000-watt Fresnel on a typical 120-volt supply pulls about 5000 / 120 = 41.7 amps, which is best represented as 41.5 amps in practical rounding. That’s why the correct choice is the around-41-amp figure. If you fed the lamp from a higher voltage, the current would be smaller (for example, ~24 A at 208 V), but on the common 120 V venue supply, it’s about 41.5 A. The other numbers don’t fit because they would require different voltages or wattage.
