Prashant Purohit: Nurturing Minds through Tutoring

Qualification:

Experience:

I have around 4 years of teaching experience and have worked as a Lecturer in Electronics and Communication Department in C.U. Shah Technical Institute of Diploma Studies, Wadhwancity from 5th August 2010 to 13th September 2014.

Approach:

I use a consistent, formal approach in evaluating my student's performance and determine the best teaching method for my students because I think correct knowledge is more important than complete knowledge. I as a teacher have the ability to analyze complex problems in a structured manner to arrive at the root cause and thereafter evolve appropriate solutions.

Question: How to convert binary to gray code and vice-versa?

Posted in: Electronics | Date: 25th Oct'15

Answer

suppose Binary is 100110 1st digit 1 as it is, 2nd digit Exor 1st digit = 1, 3rd exor 2nd = 0, 4th exor 3rd = 1, 5th exor 4th = 0, 6th exor 5th = 1 gray code is 110101 now same gray code converted to binary. 1st digit of gray code as it is. so 1st dig of gray= 1st dig of binary, 1st dig of bin exor 2nd dig of gray= 0, so 2nd bin dig = 0, 2nd bin exor 3rd gray = 0, 3rd bin dig= 0, 3rd bin exor 4th gray = 1, 4th bin dig= 1, 4th bin exor 5th gray = 1, 5th bin dig= 1, 5th bin exor 6th gray = 0 6th bin dig = 0 now binary code is 100110. got it

Question: Why length of antenna is taken as one half of wavelength or one fourth of wavelength? Why not one eighth or one sixteenth?

Posted in: Electronics | Date: 27th Oct'15

Answer

Waveforms always cuts in its max amplitude or min amp(0). So if Half wavelength means amp is zero or 1/4 of wavelength means amp is max.

Question: How to calculate the reactance of conductor of different sizes?

Posted in: Electronics | Date: 27th Oct'15

Answer

Z = R + jX Z^2 = R^2 + X^2 X^2 = Z^2 - R^2 = (V/I)^2 - (ro• L/A)^2

Question: Differentiate between distance and displacement

Posted in: Physics | Date: 27th Oct'15

Answer

I give you example for understanding this question's answer. The distace between rajkot and bhavnagar cities is 180kms. You travelled from rajkot to bhavnagar that means your displacement is 180 Kms. And you return from bhavnagar to rajkot. So your displacement is 360kms. But distace ad it is 180kms. ok...
