How do I change a resister value. For example, I want to change the default 1k value to 100ohm?

What values or abbreviations does the program use for the resistor values?

Thank you

 

you can change the values of the component in multisim by double click the component, for example you wanted to change the value of the resistor, just double click the resistor, and you can change the value there, don't forget to connect ground to the circuit, if you didn't connect the ground, it would show an error message, hope this would help you
