Questions from BTE Question Paper of Basic Electronics 2015

Hello Everyone, I am Vivek :), and in this post, I have written Questions from BTE Question Paper of Basic Electronics 2015.

The Question Paper of BE 2015, I founded in very bad condition, so I decided to write Questions instead of Scanning and uploading paper images.

So, I hope this Question Paper will be helpful for every Computer Engineering student of 2nd Semester.

PART-A

• What is a charge on the electron?
• Write the name of 2 Active elements.
• Write the name of majority charge carriers in n-type semiconductors?
• Draw the symbol of LED.
• What is the ripple factor of Half wave rectifier?
• Write one specific application of Zener diode.
• Draw symbol of PNP transistor
• BJT is______controlled______source.
• What is the value of the stability factor for voltage divider bias?
