I only need a-d thank you !!

A=23. B=33. C=133 B- 1. Consider the given circuit with R1 = R4= B $2, R2=R3= A $2, and $1= 9.0 V and $2= 12.0 V a. Draw the circuit in your paper and label current of 9V battery as in and 12 V battery as i2 and choose direction as you wish. Label loop direction as you wish too. What is current of the middle wire in terms of in and i2 (10 points) b. Write Kirchhoff's potential difference rule for left loop by following the directions labeled in part a. (10 points) c. Write Kirchhoff's potential difference rule for right loop by following the directions labeled in part a. (10 points) d. Calculate currents i1, i2 and the current of the middle wire(13)? (10 points) e. Calculate the potential difference of Ri? (10 points) f. Calculate the potential difference of R2? (10 points g. Calculate the power dissipation of R2 resistor (10 points) h. Cross sections through two long conductors of the same length and the same material, with square cross sections of edge lengths are shown in left. Conductor Y fits snugly 41 within conductor X, Rank the cross-sectional areas of X and Y? Rank the resistance of X and Y? You should show all the work to receive full credit. (10 points) X Y
