Someone please help me with this! I will mark brainliest please explain!!!

resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1 is the answer to the question
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1 is the correct answer is the correct answer to the question
