What is voltage divider circuit?
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
What is used to provide the proper voltage to a CPU?
A power supply that transforms AC to DC is used to provide the proper voltage to a CPU.
What is voltage required for desktop?
Desktop computers all come with a power supply that changes the mains voltage in your country's electricity supply to that needed inside the PC. Thus the Voltage used by your PC is the mains voltage in the country where the PC was sold.
Why used transformer in subststion?
The substation is there to convert a high voltage to a lower voltage for electricity supply. Transformers are needed to do this.
What do you understand by stabilizer explain its uses?
A Stabilizer maintains the voltage across a load constant no matter how high the current goes.It can be used to maintain the voltage across a load constant no matter the variation in supply voltage and also it can be used to maintain the supply voltage constant no matter the variation in load.
What is used to increase or decrease voltage that enters a house?
A transformer can be used, either a step-up or step-down transformer, to deliver the power at a different voltage from the normal supply voltage.
For what are high voltage power supplies typically used for?
High voltage power supplies have many uses. It is most commonly used to supply power from a device to the circuit. These are great for people who need to supply their house with power.
How much voltage loss with a dimmer switch when used for lights?
There is no loss in voltage. Voltage is constant (dependant on your supply). The dimming is as a result of of a reduction in current (ampage)
How can you get 12volts supply from speaker?
You can not. Speakers do not supply a voltage they need a voltage to operate correctly.
Where can one purchase used INOVA flashlights?
Check out a site such as Amazon for INOVA flashlights. They often have customer reviews on the flashlights and one can read them before deciding to purchase a new or used one.
How do rectifiers and transformers work in a PC power supply?
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.
What is the use of ic 7806?
IC 7806 is the voltage regulator that gives 6V dc voltage from 230V ac power supply. It is used to give power supply to the IC which operates on 6V.
