10th Class Physics Chapter 7 Basic Electronics Short Question Answer
Digital electronics devices store and process bites electronically.
The picture in our T.V. set and display terminal of most computes are cathode ray tubes.
i. Increasing strength of the battery and voltage.
ii. By increasing temperature.
Digital quantities. Quantities whose values vary in non-continuous manner are called digital quantities. Digital quantities are expressed in form of digits or numbers.
In oscilloscope filament is heated electrically. When filament is connected to voltage source, current passes through filament and get heated.
Boolean variables can have only two values 0 and 1
It is a branch of mathematics which deals with the relationships of logic variables.
Quantities whose values very in continuously or remain constant are known as analogue quantities.
Example: Temperature, time, pressure, distance and analogue quantities.
i. Displaying wave forms.
ii. Range finding
iii. Measuring voltages.
iv. Echo sounding.
v. Displaying heartbeats.
i. There is no interference in digital signal
ii. Its easy to read digital quantities.
In the electron gun the grid is used to control the flow of electron, thus control brightness on fluorescent screen.
NAND gate is formed when AND& NOT gate are connected one after the other .If AND gate show 0 output, then NAND gate will show 1 output. So we can say NAND agate is reciprocal of AND gate.
An instrument which is used to display the magnitude of rapidly changing electric current or potential.
A vacuum tube used to accelerate electrons which emit from the cathode by applying high voltage between cathode and anode is called ray tube.
It is used to investigate the properties of electron beam.
Filament is heated for emission of electrons. If metal is heated to a high temperature, some of free electrons may gain sufficient energy to escape metal surface.
Logic gates in electronic circuits are used to do useful tasks. These circuits usually use light depending resistors to keep inputs LOW. An LDR can act as a switch that is closed when illuminated by light and open in dark.
A large potential is applied between anode and cathode to accelerate the beam of electrons.
