## Homework Statement

I have just done a lab and im very confused on what to do.

2 batteries 3 resistors - 3 currents -> recieved by testing.

So i have to do the theoretical equations

ive done the lab and got the currents

and so far ive came up with this.

( -V2 + Vt1 - V1 ) for the first loop

-> also (- i 2 R 2) + Vt1 + ( - i 1 R 1) idk if this is correct

and

( V3 - Vt2 + V2)

and ( i 3 r 3 ) - Vt2 + ( i 2 r 2 )

im not sure what im supposed to do. Plug in the givens?

i think i need two kirchhoff equation

1 node equation .

just very confused

Vt1 - 5v

vt2 - 4 v

R1 - 750 ohms

R2 - 100 ohms

r3 - 750 ohms

am i supposed to just find the equation? or is there a variable thats not given?

i want to LEARN how to do it so if someone could explain it would be nice

thanks in advance

## Homework Equations

The only one i know is

V = IR

and some others for kirchhoff which i came up with going according:

1. I = current going against "Pattern" (ABCDE) = -

I = current going with the "Pattern" = +

## The Attempt at a Solution

I have given this above
