Varying voltage into a multisim zenerdiod sample circuit.

[Sump]

Hi

I wonder how i can get a varying power source into the attached sample circuit. A very basic question but would be glad if someone could help me 🙂

I want the input voltage vary like this:

−15V < u < 15V


Thanks in advance.

O.K. I have your circuit. Keep in mind that this may not be the only way to do this, but it is the simplest.

I just hope I didn't do your homework for you. If I did do I get the A. (I am joking of course.)

Here's the modified circuit:

Thank you. 🙂
