A circuit having a supply voltage of 240 volts and a resistance reading of 100 ohms will have an amperage reading of ____________.

Explanation:
Current follows Ohm’s law: current equals voltage divided by resistance. With 240 V across 100 Ω, the current is 240 ÷ 100 = 2.4 A. So the amperage reading is 2.4 amperes.
