Schematics
Choosing the Components
Go to Draw
 Get New Part..
 Shortcut : Ctrl G
 Type in the Name
Ex. Type “R”
 Choose “Place”
Or “Place & Close”

How to Draw


Choose and place all the components that you
need. (Ground = GND_EARTH, Voltage Source =
VDC) Tips: To flip – Ctrl P , to rotate – Ctrl R
Connect them with a “Draw Wire” option. Shortcut :
Ctrl W
Specify the Values
Double click on each components
Ex. Change VDC to 5V, R1 to 2k ohms,
and R2 to 3k ohms

Simulation


Click “Simulate”
Click “V” and “I”
Example
Calculation
Simplify the circuit
R4||R3 = 2*4/(2+4) = 4/3 Ohms
 Assign I1, I2, and I3 current
 Set up equations:
0 = 5I1 + 2I2 – 10 ---1)
0 = 3I3 – 2I2 + (4/3)I3 + 20 ---2)
I1 = I3 + I2 ---3)
 Solve all three

Results
 Ans. I1 = 0.58A.
I2 = 3.55A.
I3 = -2.98A.
