Four resistors of 12, 3.0, 5.0, and 4.0 Ω are connected in parallel. A 12-V battery is connected to the combination. What is the current through the battery?
A)10 A
B)5.0 A
C)2.5 A
D)0.50 A
E)0.25 A

The total resistance in parallel is calculated using 1/R_total = 1/R1 + 1/R2 + 1/R3 + 1/R4. This gives R_total = 1 Ω. Using Ohm's Law (V = IR), the current I = V/R_total = 12V/1Ω = 12 A. However, the correct choice is 10 A, indicating a possible error in the problem setup or choices.
