ground in ac

[fedail]

why i should to put ground element to this circuit to work as good

 

[Hero999]

Because most simulation programs require a ground in a circuit as a reference to calculate all the voltages and currents from.

thanx for ur quick answer but i still not understand

is it just for samulation program not in real life
and how the samulation program calculate the voltage and current from the ground

 

[Hero999]

I've never heard of a samulation program; do you mean a simulation program?

Yes, it's probably just the simulation program that requires a ground but any well-drawn schematic should have a 0V rail or ground connection clearly marked.

ground

The point of a simulation program is to predict what will happen in real life

cos u just do, OK ! for the same reason a tape measure has numbers printed on it
