Hi.I have a problem using DC voltage in proteus.In the attachment photo you see dc voltage in proteus has only one side for wiring and that's the +ve side.but there is no -ve in there.but when I came to analyse this circuit I had to find the current through the -ve side of the voltage source to ground.If proteus voltage source is virtually grounded then that means current will be zero because ground to ground same potential.but there current must be 0.0025A . so please help

 

Did you try "Battery" or "VSOURCE"?

I didn't use BATTERY AND VSOURCE earlier. now I just used it and problem is solved.thanks a lot. While using current control current source in proteus input needs a transfer fucntion.How can I put 4A current source in proteus and how to give it a value?

Did you try using CSOURCE?
