Question
Given a 10-V power supply, would a 20-ohm resistor and a 5-ohm resistor need to be arranged in parallel or in series to generate a current of 2.5 A? How much current would move through each resistor?

10/2.5 = 4 ohms effective resistance.
Clearly, the two given resistors cannot be in series, since their sum is 25 ohms.
1/20 + 1/5 = 1/4
so they are in parallel

so 4 would have to generate through each resistor?
