Reverse Bias

Question 25

A)Prevents further recombination

B) .7 Vlots

Barrier Potential :The natural difference of potential that exists across a on junction.

Answer 25

Barrier Potential

Question 26

Recombination

Answer 26

A term to used to describe the process of a free electron giving up its energy and returning to a valence band orbit.

Question 27

How to calculate Supply Voltages from a secondary transformer?

Answer 27

If the transformer center tap is used then only use half of the secondary input voltage supply time 1.414.

If the transformer center tap is not use all then use all of the secondary input voltage supply time 1.414.
