IE Group 4 - Assessment 2

Instruments that consume very less power as compared to analogue instruments.

• Digital Instrument

• Analogue Instruments

• Steel Scale

• Multimeter

The accuracy of the digital electronic instrument is very much (a)   .

it is used for converting the non-electrical or physical quantities (temperature, displacement etc.) into an electrical quantity like voltage, current etc. which is easily measured by the meter. The transducer is not required for the electrical input.

• Micrometer Gauge

• Transducer

• Signal Modifier

• Display Device

It is used for modifying the input signal of very weak strength.

• Display Device

• Transducer

• Signal Modifier

• Micrometer Gauge

is used for showing the measure and quantities in the numeric form. Mostly,  LED or LCD is used as a digital display.

• Signal Modifier

• Display Device

• Transducer

• Micrometer Gauge

is a semiconductor light sensor that generates a voltage or current when light falls on the junction

• Solar Cells

• Photo Diode

• Optical Fiber

• Light-Emitting Diodes

is a P-N semiconductor diode in which the recombination of electrons and holes yields a photon.

• Laser Diodes

• Optical Fiber
