A 20-ohm resistive load is connected to 240 volts. What current does it draw?

Texas Journeyman exam practice question · Branch Calculations & Conductors

A 20-ohm resistive load is connected to 240 volts. What current does it draw?

12 amperes
B20 amperes
C8 amperes
D48 amperes

Why A is correct

Ohm's law gives current as voltage divided by resistance: 240 ÷ 20 = 12 amperes. Keep units consistent and use only the factors stated; no optional method or unstated demand factor is assumed.
