Answer:

Explanation:

To find this current we need to use Ohm's law. The total resistance in series combination is just a sum of both resistors Rt=R1+R2=3+4=7Ω. I=V/Rt=12/7A≈1.714A. To find the voltage across each resistor we can use Ohm's law again and V1=IR1=12/74=48/7V≈6.86V; V2=IR2=12/73=36/7V≈5.14V.
