One of the advantages of using transformer coupling in a half-wave rectifier is that it allows the ac source to be directly connected to the load.
A zener diode can be used to provide voltage regulation in a power supply.
The conduction band is closest to the valence band in
What is the current through the zener diode?
The voltage where current may start to flow in a reverse-biased pn junction is called the
The diode's characteristic curve shows that current increases when voltage increases.
The positive lead of a diode is the cathode.
If a bridge rectifier is used, it is not necessary to use a transformer.
It is not possible to use a half-wave rectifier circuit without a transformer.
Electrons in the conduction band are the only ones that are included in the electron current flow.
The dc current through each diode in a bridge rectifier equals:
Doping semiconductive material is the process of putting a small amount of pentavalent or trivalent atoms in with tetravalent atoms.
The forward biased characteristics of a zener diode are the same as those of a diode.
Breakdown voltage and peak inverse voltage are the same.
Special diodes designed to conduct in the reverse direction are called _______________ diodes.
A common problem with rectifiers is open diodes.
The small amount of ac signal present on the output of a filtering network for a dc power supply is known as ________.
___ occurs when a pn junction is first formed.
