A 28V DC system powers a 14Ω load. What is the current?

Explanation:
Current in a DC circuit follows Ohm’s law: I = V / R. With 28 V across a 14 Ω load, I = 28 ÷ 14 = 2 A. So the current is 2 amperes. Quick checks: 0.5 A would require 56 Ω, 14 A would require 2 Ω, and 28 A would require 1 Ω. The 14 Ω load gives 2 A, matching the calculation.
