Two light assemblies require 3 amperes each during operation at 24 volts. The total current is

• A. 3 A
• B. 6 A
• C. 9 A
• D. 12 A

Answer: (B)

When multiple paths are connected to the same voltage source in parallel, the currents from each path add together to form the total current drawn from the source. Each light assembly draws 3 A at 24 V, so with two assemblies in parallel, the supply must provide 3 A + 3 A, which equals 6 A. The 24 V rating means both assemblies see the same voltage, not that the current stays the same; that’s why currents sum in parallel. If they were in series, the current would be the same through both at 3 A, but that isn’t the case here.
