You have just walked into a room where electrical engineers were analyzing circuits. They wrote two equations on the whiteboard that represent Kirchhoff's loop law for a multi-loop circuit: E1-IaRa-IbRb=0 IbRb+E2=0 You aren't sure if the equations are correct (maybe the engineers were discussing impossible circuits), but you decide to learn about the circuit that is represented by the two equations above. Assume the symbols for current are unknown, but the EMFs and the resistances are known. The EMFs and resistances are positive as usual. Known: E1 , E2 , Ra , Rb Draw the circuit diagram (using the correct symbols for batteries and resistors) that corresponds to the loop law equations above. You will add more and more to this diagram as this problem goes on, so make it large. On your diagram, draw and label arrows next to each resistor to indicate the amount and direction of conventional current. Make your directions and labels consistent with the loop equations. For example, use iA and iB, and don't forget direction! Also draw another arrow to represent the direction of current going through E2 battery; it is okay at this point to just guess this direction if you don't know it yet; label that current i2. Based on your three current arrows on your diagram (iA,iB, and i2), write a new equation that represents Kirchhoff's junction law for the circuit. Make sure your equation is consistent with your three current arrows in the diagram. Now you have three equations and three unknowns. Cool! This is a practice exam. I have more questions because they all depend on the question before I hope you can. help me get this started

Question

You have just walked into a room where electrical engineers were analyzing circuits. They wrote two equations on the whiteboard that represent Kirchhoff's loop law for a multi-loop circuit:

E₁-I_aR_a-I_bR_b=0

I_bR_b+E₂=0

You aren't sure if the equations are correct (maybe the engineers were discussing impossible circuits), but you decide to learn about the circuit that is represented by the two equations above.

Assume the symbols for current are unknown, but the EMFs and the resistances are known. The EMFs and resistances are positive as usual.

Known: E₁, E₂ , R_a, R_b

Draw the circuit diagram (using the correct symbols for batteries and resistors) that corresponds to the loop law equations above. You will add more and more to this diagram as this problem goes on, so make it large.
On your diagram, draw and label arrows next to each resistor to indicate the amount and direction of conventional current. Make your directions and labels consistent with the loop equations. For example, use i_A and i_B, and don't forget direction! Also draw another arrow to represent the direction of current going through E₂ battery; it is okay at this point to just guess this direction if you don't know it yet; label that current i₂.
Based on your three current arrows on your diagram (i_A,i_B, and i₂), write a new equation that represents Kirchhoff's junction law for the circuit. Make sure your equation is consistent with your three current arrows in the diagram.

Now you have three equations and three unknowns. Cool!
