Kirchoff Loop Rules
1. |
The total
voltage change in a loop = 0
|
2. |
If direction
through a battery hits negative end (small line) then positive end
(large line) it is positive, otherwise, it is negative.
|
3. |
If the direction
through the loop is the same as the current direction, V = - IR;
otherwise,
V = IR
|
V1
+ I5R5 - I3R3
=
0
A is wrong
V2 - I1R1 -
I6R6 =
0
B is
correct
V1 + I6R6 -
I2R2 - I3R3
=
0
C is wrong
V1 + V2 - I4R4
=
0
D is wrong |
