I am lost on the work on how to get this answers. I need help with understanding these three and I will be good! please help me out!! Thank you!

13. R and 2R problem. please label anything and why you get the numbers

Taking R - 2.30 id]. and 5 - 490 V In the gure shown below, determine the magnitude and direction of the current In the horizontal wire between a and e. magnitude mA. direction 16.

The figure shown below is an end view of the conductors, The direction of the current is into the page at points A and B (indicated by the crosses) and out of the page at C and D (indicated by the dots). Calculate the magnitude and direction of the magnetic field at point P, located at the center of the square with edge of length 0.200 m.
