Hi everyone,
Just a quick question that was bugging me...
If i was asked to draw the voltage output vs time of an induction coil...would it be absolute value sine curve??
Secondly i absolutely don't understand how in Hertz experiment, what the sparks jumping across have anything to do...
Is there anybody out there that can help me??
Ok in a TV set, the electrons that are emitted come from the heating filament. Now as i read on this site...the heating filament replenishes its stock of electrons from an AC supply. I understand that bit. So there is an AC supply of electrons to...
Cathode Rays
Hey...i really don't get this part of dischage tubes...a potential difference is applied and the 2 electrodes are cathode and anode...now if electrons are produced and emitted at the cathode...shouldnt they always hit the anode...since they would need to hit the anode to complete...
