How to create connections?

I'm creating an analysis for a full-bridge rectifer.

My goal is to determine the no load voltage. This is being used for a school project.

My connections from the diode bridge to the load and scopes is not connecting properly. I'm new to Simulink so this may be why.

On the left (in blue) you have used blocks of the Simscape Foundation Library.

On the right (in black) you have used blocks of the Simscape Electrical Specialized Power Systems library.

Unfortunately, you cannot mix and match blocks from both libraries.

I suggest you only use blocks of the Simscape Foundation Library, or all categories under the Simscape Electrical library, apart from the Specialized Power Systems.

The two blocks you want to use on the right-hand side, can also be found in the library outside Specialized Power Systems.

• Resistor: Simscape - Foundation Library - Electrical - Electrical Elements
• Voltage measurement: Simscape - Foundation Library - Electrical - Electrical Sensors

For some specific use-cases it is interesting to use the Specialized Power Systems library, but especially if you want to add other physical domains the other blocks are the way to go.
