Hi Team

I simulated the following circuit and found VF1 has output but Vout doesn't have output. Can you help show your comment why this happen?

Hey Harry,

it looks like Vout is not connected to the wire. Try moving the voltage meter away from the wire and drawing the connection from the end of the voltage meter pin back to the wire. If the wire was connected, there would be a junction dot (like above c4).
