connected to +ve terminal and n- type (cathode) is connected to –ve terminal of the supply voltage‚ is known as forward bias. The potential barrier is reduced when diode is in the forward biased condition. At some forward voltage‚ the potential barrier altogether eliminated and current starts flowing through the diode and also in the circuit. The diode is said to be in ON state. The current increases with increasing forward voltage. When N-type (cathode) is connected to +ve terminal and P-type

knowledge about the mysterious green glow when he created a bent Geissler tube in 1875. He noticed that the glow was the most intense opposite the negative electrode‚ also called the cathode. Crookes reasoned that rays traveled from the cathode and then hit the end of the tube. Because of this‚ Crookes named these rays cathode

interior of the atom. At the Cavendish Laboratory at Cambridge University‚ Thomson was experimenting with currents of electricity inside empty glass tubes. He was investigating a long-standing puzzle known as cathode rays. His experiments prompted him to make a bold proposal: these mysterious rays are streams of particles much smaller than atoms‚ they are in fact minuscule pieces of atoms. He called these particles corpuscles‚ and suggested that they might make up all of the matter in Atoms. It was startling

Laboratory Handbook Stage 1 Semester 2 ENG1030M Electronics Applications Project Electronic Applications (ENG1030M) Module overview This laboratory based single module (100 hours total) consists of one 3 hour session per week and has 3 main parts. Each part involves practical and written work‚ these are shown below in chronological order. You should be advised that that the lab sessions use up 36 hours and therefore you will be expected to use the remaining 64 hours in background work

investigate cathode rays(the electrical discharge emitted from an electrode under high fields in a gas at low pressure). Several german physicists believed that cathode rays were waves. Hertz tried to show that they could not be particles‚ because in his experiments the cathode rays were not deflected by an electric field. However‚ Thomson repeated the experiment in a vaccum‚ in which there was no polarisable air to mask the electric field and demonstrated that electric fields could deflect cathode rays

not only were their electrons and cathode rays traveling toward the positively charged end (anode)‚ there was a third ray that traveled away from the anode end to the cathode. While observing this ray he noticed how it passed through the holes‚ or channels of the cathode. He named this ray the “canal ray”. Since the canal rays traveled in different directions from the cathode rays he noted the rays must have opposite charges. Before Eugen discovered the canal ray he attended the University of Breslau
