answers 2025 latest update.
Rectification is the process of - answer converting AC pulsating to
DC
Electrolytic capacitors are often used as power supply filters
because they provide - answer high capacitance in small package
The front-to-back ratio of a good diode can be checked - answer
with an ohmmeter and should be greater than 100 to 1
the capacitors in the filter circuit of a power supply - answer
delivers energy to the load between peaks of the DC input
In normal applications, a zener diode - answer is biased so that its
cathode is positive with respect to it anode
The emitter of a PNP transistor is identified on the schematic
diagram by - answer an arrow pointing toward the base
In most power supply applications, full-wave rectifier circuits are
preferred over half-wave rectifier circuits because the full-wave
rectifiers - answer are more efficient and easier to filter
Leakage current through a diode result from - answer minority
carriers in the N and P type materials
, Impurities are introduced into pure semiconductors by a carefully
controlled process called - answer doping
in a typical zener diode shunt regulation circuit where the source
varies, the voltage across the - answer series dropping resistor
varies
High gain transistors - answer require a small base current to
control a large collector current
The quiescent operating point of a transistor amplifier circuit is -
answer determined by the DC bias level, selected to be near the
center of the load line, about half of the supply voltage level, (ALL
the above)
A full-wave rectifier circuit - answer requires two or four diodes
The most important characteristic of semiconductor atoms is the -
answer number of electrons in the outer shell
The majority carriers in P type material are - answer holes
the current through a zener diode biased for normal applications -
answer must be limited by a series resistor
You can reduce ripple in the output of any power supply by - answer
increasing the capacitance of the filter circuit
Free electron in semiconductors - answer are introduced by
impurities
