A: The output voltage a 7805 can becomes a 1 voltage regulator of higher voltage the 5 volts if so chosen. However it can never becomes less then 5 volts not unless a negative voltage source is found.

Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
What type of voltage regulators r there?
series and shunt voltage regulators
What is LM 105?
LM105 series are monolithic voltage regulators, basically about 4.5 volts output, but which can be configured to deliver up to 40 volts.
Are voltage regulators universal?
no.
What is a regulated variable direct current?
Voltage regulators that are adjustable are common, for example the LM338, which can pass up to 5 amps with a suitable heat sink, and the output voltage is set by two external resistors connected to the regulator. A variable resistor can be used to make the output voltage directly adjustable.
What is the purpose of voltage regulators?
Voltage regulators are intended to keep a certain voltage level, which is important for most electronics to run properly. Without a voltage regulator, if an electronic, such as a computer, receives too much voltage then it can fry the components.Controls output of alternator so battery does not over or undercharge Should control voltage range from (when engine running) 13.8-14.2 volts Without voltage regulator: Voltage could go to 18-24 volts causing electrical components to burn out
Why voltage of transformer go up beyond the set voltage when carrying out transformer test?
Transformers without regulators in them will output voltage depending on the voltage coming in. For instance if you have a 230v to 110v transformer then you will have a ratio of 23:11 this means for every 23 turns in the transformers primary side you will get 11 turns on the secondary, so if you have an input voltage of 247v then the output voltage will be around 118v, conversly if you have an inout voltage of 221v then the ouplut voltage will be around 106v.
What is the main use of ic 7812?
Here is circuit 9V power supply regulator with battery 12V backup system. Use IC 7812 and 7805 control voltage output by R3 1K output 9V 1A max. This is a 9V power supply which will work even on power failure. It uses a rechargeable battery and regulators. A transformer with 15-0-15 AC volts output is required. In the first regulator U1 the output is lifted up by 1.4V and in the second regulator U2 by a resistor divider. In the second regulator the voltage across resistor R3 is 5V, so the current is 5V / 1K = 5mA this adds to the quiescent current of 5mA from the regulators ground terminal and flows into the resistors R1 and R2 in parallel which form 404 ohms, 10mA thru 404 ohms is 4V. So the output will be 5 + 4 = 9V. Note that the charge and discharge paths of the battery are separated with diodes.
What is the difference between IC7905 AND IC7805?
Both IC 7805 & IC 7905 are voltage regulators, IC 7805 is Ic 78xx series while IC 7905 is Ic 79xx series with xx representing voltage output
What is mean by AC voltage regulators and where you can apply it?

Where is the Voltage Regulator on a 1996 Nissan Altima?
Most voltage regulators are inside the alternator.
Where is the voltage redulator on a jeep cherkee laredo1994?
Voltage regulators are integrated into the alternators these days.
