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
( 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
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
