ATT Test 8
What are five parts of a strength deliver?
Input, rectifier, filter, regulator, safety
Which parts of a power deliver are non-compulsory?
Regulator and protection
What is the reason of a energy supply?
To convert AC electricity into easy DC energy
What does the enter of a strength deliver do?
Step up or down the AC enter voltage
What does the rectifier do in a energy deliver?
Changes AC into pulsating DC
What does the filter out do in a power supply?
Changes pulsating DC into clean DC
How form of additives do filters use?
Reactive components
What does a regulator do in a power deliver?
Keeps the output voltage at a consistent level notwithstanding changes in load modern
What does the protection circuit do in electricity deliver?
Prevents harm to electricity supply if load turns into defective, limits or disables output
The half wave rectifier is similar to what circuit?
Series limiter
Which rectifier is the least green the usage of handiest half of the input?
Half-wave
, Which rectifiers require two input indicators a hundred and eighty tiers out of segment?
Full-wave and bridge
Which rectifier makes use of a middle tapped transformer?
Full wave
How is frequency decided for half of wave rectifier?
Output frequency is same as input frequency
How is frequency decided for complete wave rectifier?
Output is twice the enter frequency
How is frequency decided for bridge rectifier?
Output is twice the enter frequency
What is the purpose of collection voltage regulators?
To alter voltage drop to maintain V out at constant level
In a sequence voltage regulator, V out INCREASES whilst what occurs?
Load current decreases OR DC input increases
In collection voltage regulator, V out DECREASES when what occurs?
Load contemporary increases OR DC input decreases
If load current decreases or DC enter will increase, what desires to be done to preserve
consistent degree of V out (series volt regulator)?
Increase R1 resistance to growth voltage drop on R1
If load modern-day will increase or DC input decreases, what desires to be executed to hold
consistent level of V out (collection voltage regulator)?
Increase R1 resistance to decreases voltage drop on R1
What is the reason of parallel voltage regulator?
Adjust modern drift to keep V out at steady degree
