If i have a light bulb , and it has a tungsten filament and when i turn it on its gets hot ,
If i hook a lead to the filament and then put the anode away from the filament can i get electrons to flow through the vacuum , assuming this is done with DC current. If we used 2 different power supplies one to heat it and the other to create a potential difference.

Do you mean like a heated filament in a CRT (TV picture tube)?
