Hello, i am just learning to use ltspice and i want to set up an ac circuit. "i(t) = 3 cos200t mA." How can I add this in ltspice for current source ?

I want it to be like this. How did you configure the current source to work like this? I don't understand how to add the cos.

 

hi,
Use F2 to show the Menu, use B2i,
Add the B2i to the circuit.
Right click on the B2i symbol, type in your equation.

Thank you so much. One last question why did you divide it with 1000 ?

 

hi,
You asked for milli-amps. mA

You could also multiply the expression by 1mA to get the same result, of course.
