1. Define electronics?
2. Current is flow of electrons from higher potential to lower, then why we represent direction of current from Positive to negative?
seems to be simple but i ask this in interview, if you can answer this properly without any material i will give more.
No i am not testing everyone here.
The theme of this post is to share some questions and answers asked in the interview and test.
It would help all of us and specially me to improve my basics.
1. What is the use of capacitor at the input and output of power supply, Usually there are 2 cap in parallel, 1. a higher value of 10 uf/63v and other is small value of nf. why 2 cap are required.
2. What is efficiency of regulation.
3. If i use 5V regulator, how do i decide the min and max voltage to the regulator?
4. What is the use of shunt capacitor and resistor.
