How do I select different value of resistances depending on the control input.

I wish to simulate a system with changing resistive loads. I want to select different value of resistance depending on the value of my control signal. How can I achieve this?

We need more details to be more helpful. Are you working in matlab, or simulink. What's your control signal? What kind of change to the load do you expect from your control signal?

An option is to create your own function with the switch-case statement
switch control
case 1
resistance = 100;
case 2
resistance = 1000;
case 3
resistance = 10000;

I am now using a 'variable resistor' block from simscape and that has solved my problem.
I appreciate help from all of you. Thanks
