APPHEM-1G4KQL

In the circuit above, a current of magnitude $I_1$ travels to the right through $R_1$ and a current of magnitude $I_2$ travels from top to bottom through resistor $R_2$.

Which of the following could be used to analyze the circuit shown in the figure above?

Select all that apply.

A

$\mathit{2V – I_1 R1 – I_2 R_2=0}$

B

$\mathit{2V – I_1 R_1 – I_2 R_2-V – I_2 R_3=0}$

C

$\mathit{2V – I_1 R_1 – (I_1 – I_2) R_3 – V=0}$

D

$\mathit{2V – I_1 R_1 – (I_1 – I_2) R_3 + V=0}$

E

$\mathit{2V – I_1 R_1 –I_2 R_3 – V=0}$

F

$\mathit{V – I_2 R_2 + I_2 R_3 =0}$

G

$\mathit{-V – (I_1-I_2) R_3 + I_2 R_2 =0}$
