Hi hamzan,

welcome to the forum!

Ramón Jaramillo already wrote such an example. It's with colors but you can easily remove the colors. As it's your homework, you should at least work something with it. You should be able to understand it. The teacher may ask you. If you have questions about a specific detail, just ask.

If you click on "Open in writeLaTeX" you can directly edit it online.

Here's another electric circuit TikZ example I made, showing what I like: at first, placing all nodes worth names in a matrix like way, then connecting the nodes by elements.

If you need to know how to make a specific detail, let us know.

[Stefan Kottwitz]

I saw you follow-up question to the crosspost. As I started here, I simply continue here.

What I would improve at first:

• Avoid having coordinate numbers everywhere. Working on it, it's hard to remember what (3.5,4) actually means. It's better to use a name such as (E2) for it, so you always know the meaning. You can even label the coordinates, so no need for extra nodes.
• Use length or macros, build coordinates on parameters, which makes changes easier, such as shifting a whole row of coordinates upwards.
• Use styles for all what has formatting or color, so later re-styling is much easier.
• Let TikZ calculate points such as midpoints, so it will adjust automatically when you change coordinates.
• Use spacing to have a better readable code.

Here's a complete sample, adding + and - and the colored lines with rounded corners and arrow to your code. Not perfect, but to show what I mean. The option american current source should be removed for the desired label positioning near the line instead of the component.

Dear Admin and folks,

I would like to know if we can inverter(three phase) switching configuration with operating switches and current flow? mean at any given instant only 2 switches operate with one connected to positive supply and other to ground. Like if UVW are phases with 6 switches , U+W- conduct. I just started to use Latex today so i am not aware of complete commands to draw a electrical circuit.Please guide me through this.
