If an 8-ohm resistor has 12 V applied, the current is 1.5 A. If the voltage is increased to 24 V, the current becomes:

Current through a resistor scales with voltage when the resistance stays the same, because I = V / R. With an 8-ohm resistor, 12 V gives I = 12/8 = 1.5 A. If the voltage is increased to 24 V, the current becomes I = 24/8 = 3.0 A. Doubling the voltage doubles the current for a fixed resistance, so the current is 3.0 A.
