The term space charge is applied to the cloud of electrons that is formed in the interelectrode space between cathode and plate. Since it is made up of electrons, this cloud constitutes a negative charge in the interelectrode space that has a repelling effect on the electrons being emitted from the cathode. The effect of this negative space charge alone, therefore, is to force a considerable portion of the emitted electrons back into the cathode and prevent others from reaching the plate.

A diode is a two-element electron tube that consists of a cathode and an anode or plate acting as an electron collector. By applying a positive voltage to the plate of a diode, an electric field is established between cathode and plate that attracts electrons emitted from the cathode to the plate.

Current transformers are used for operating ammeters, wattmeters, and other measuring devices. They produce in the meters a current lower than the measured current but proportional to it.
Current transformers also insulate the instrument from the circuit which is being measured. This is necessary for high voltage circuits.

Microelectronics today encompasses thin-film, thick-film, hybrid, and integrated circuit 1________________. These approaches (and combinations of them) are being applied in 2____________ branch of electronics.
Integrated circuits that combine all the 3__________________ of a complete electronic circuit on a single chip of silicon can be produced. The implications of this in the microelectronic evolution are easily 4_______________. Let us compare a conventional J/K flip-flop circuit incorporating solid-state discrete devices and the same type of circuit employing integrated circuitry.
