How to change load(resistance) while simulation is running

Greetings,

I intend to change the load such as change output R value from x to 2x. However, I should do this while simulation is running in full swing. The question is, how can I change resistance value at the load from x to 2x while simulation is running?

Thank you in advance.

The easiest way is to use the switch block. You can either use simulation time to determine when to switch or define some conditions (i.e., current goes above 0.3 A).

Can you give a visual example or sketch on how to benefit simulation time to determine when to switch.

It would be appreciated.

Below is a simple example where magnitude of sine wave is changed depending on time. Upto 3 sec, the amplitude is 1 after 3 sec, amplitude is 5.

Thank you. I understand that now. One more question; Is there any way to do it with simspace components?

[Aquatris]

I am not familiar with simspace so I cannot be of help for that.

Okay. It works for me. Thank you very much for your help.
