Write down the Kirchhoff Junction equation and solve it for I, in terms of I₂ and I3. Write the result here:
1₁ = 12-13
R₂=552
R₂ = 132
13
Write down the Kirchhoff Loop equation for a loop that starts at the lower left corner and follows the perimeter of the circuit diagram clockwise.
- IzR3 − LR₁ + 14
+ 10
Write down the Kirchhoff Loop equation for a loop that starts at the lower left corner and touches the components 4V, R₂, and R₁.
0 = 4-1₂R₂-11R₁
The resistors in the circuit have the following values:
R₁ = 12
Solve for all the following (some answers may be negative):
I₁ = 27.78
X Amperes
1₂ = 28.84
X Amperes
13 = 1.060
X Amperes
NOTE: For the equations, put in resistances and currents SYMBOLICALLY using variables like R₁,R₂,R3 and 11,12,13. Use numerical values of 10 and 4 for the voltages.
