Formula for efficiency of half wave rectifier
I came across this formula for rectification efficiency of half wave rectifier:
η= (40.6 *resistance of load resistor )/ (resistance of load resistor+ resistance of secondary of transformer + ...

How could the Gate-Source potential difference be neglected?
I’ve been reading the book
Electronic Principles by Malvino
In the Voltage-Divider bias section of JFET, if gate current is negligible then how did Gate Voltage attain a negative value, given Vdd ...

What is the reason of difference in distributed gate thyristor design
As in the pictures, they use different designs (current rate, voltage rate etc. are same.)
What is difference between these two designs?

Identifying parts of a transistor die
In books, I have studied that in a Transistor, the Base is the layer sandwiched in between Collector an Emitter. Wikipedia also mentions that
"The base is physically located between the emitter ...

BJT Early effect and the small signal model
As the collector-emitter voltage changes, collector current changes due to the Early effect so the base current must also change.
In the small signal model, we only account for the change of collector ...
