hello iam begginer in proteus
i need a bidirectional power generator something like this image
**broken link removed** but I don't know where to find it?I just know the location of these generators **broken link removed** which is not useful in the case because they can not wired at two sides
any help?thanks
You can use the sinusoidal wave generator (sine) which has only one connection point (signal), the other end is already connected to the gnd.
The second solution is to use a VSINE component which is exactly as your first picture, you can find it in the components (opamp icon under the arrow, second icon from the top and there press letter P to pick component).
