For an 8-foot long show window, the load is 1600 VA. Which of the following is a correct representation of this calculation?

For an 8-foot long show window, the load is 1600 VA. Which of the following is a correct representation of this calculation?

• A. 1600 VA
• B. 800 VA
• C. 2000 VA
• D. 1800 VA

Answer: (A)

The load is expressed as apparent power in volt-amperes, and when a total load is given as 1600 VA, that value is the correct representation of the calculation you’re using. The 8-foot length isn’t used to change the total unless you have a per-foot density to multiply by length, which isn’t provided here. So the total load remains 1600 VA. The other numbers would only be correct if you had different data (like a per-foot density or a different total), which isn’t the case in this scenario.
