solve a through f

1. Consider the circuit shown to the right. a. How many different unique currents will there be in this circuit? b. Write the junction rule for this circuit. c. Pick a complete loop (there is more than one option) around the circuit and draw it below (just the loop not the whole circuit). Include arrows to indicate the direction you are going around the loop. Also indicate each current in different part of the loop (name and direction). d. How do you determine whether AV is positive or negative for a battery as you \"go around\" this loop? How do you determine whether AV is positive or negative for a resistor as you \"go around\" this loop? e. For your loop, write the loop equation below. f. Optional: If time permits. Write a second loop equation and solve the system of equations to find the currents through each resistors
