What is CRO? |
Fullform of CRO is Cathode ray Oscilloscope. It gives visual representation of electrical quantities like voltage, current, etc. |
How are cathode rays produced? |
Cathode rays are produced when the electrons hit the fluorescent screen. |
What are the types of waveform? |
Types of waveform are triangular, square and sine waveform. |
What is time-base circuit? |
Time base circuit is used to produce sawtooth waveforms. |
What is sawtooth waveforms? |
It is type of wave in which the voltage varies linearly with time and then drops and cycle continues. |
Applications of CRO |
CRO is used to measure current, voltage, frequency, resistance, impedence, admittance, power Factor. |
What are channels? |
Channels are used to compare different waveforms. There are two channels. |
What is blanking circuit? |
Blanking ckt is used to change the potential between the cathode and the screen grid of the cathode Ray tube. |
State malus law |
Malus law states that the intensity of plane polarized light that passes through analyser varies as the square of consine of the angle between axis of of polariser and analyser. |
What is polarization? |
Polarization is the process which causes light to vibrate in single plane. |
What is Polaroid? |
Polarid is a material which polarizes light. |
What is polarizer? |
Polarizer is an optical device which converts unpolarized light to polarized light. |
What is analyser? |
Analyser is an optical device which checks whether the light is polarized. |
Types of polarisation |
Linear circular elliptical |
What is Atom Economy? |
Atom economy is how many atoms are incorporated into the products and how many wasted. |
Difference between esterification and transesterification? |
Esterification is used to produce esters while transesterification is used to modify esters during chemical reaction. |
Synthesis of Biodiesel from Vegetable oil |
Triglycerides can be easily broken down into glycerol and fatty acids this is called as transesterification to produce Biodiesel. |
What is Nebulizer |
it breaks up the sample into atoms |
Proximate Analysis |
proximate Analysis gives approximate composition of components in the coal. |
Ultimate Analysis |
proximate Analysis gives approximate composition of components in the coal. |
Moisture content |
it controls the rate of combustion. |
Volatile matter |
it helps in initial combustion. |
Ash content |
higher is the Ash content lower is the calorific value of coal. |
