What to use to power a sodium bulb?
Sodium lamps use a ballast that can be powered from multiple voltage supplies. The ballast has tri or quad tap primaries and you select the tap for the voltage that is on hand.
Can you use a 2.0 amps power supply for a 1.0 amps router?
As long as the source voltage power supplies capacity is larger than the device's demand then it can be used.
Are fans in computers ac or DC?
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
How does DC power work in a power plant?
well u just have to fart and it will work ugly person
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
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.
What is Hyacinth Technology?
Hyacinth Technology makes high voltage power supplies.
What is special about AC power supplies?
AC power supplies are power supplies that use Alternating Current, which means that the current repeatedly changes its direction. AC power supplies are usually mains supplies as they are at a high voltage. Often filtering takes place between the mains supply and the device.
What supplies power to a computer?
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
What devices typically use DC current to operate?
cell phones, laptops, desktops, anything that uses a battery. most power supplies convert AC to DC at a regulated voltage and current.
Where should i go to buy high voltage power supplies?
There are many companies which manufacture high voltage power supplies and the type would depend on what you want to use them for. I would suggest contacting your local electricity company for more information.
What does input volts and output volts mean?
The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.
How expensive is it to build a high voltage power supply?
There are many guides on the internet for building a high voltage power supply. The average cost for building one of these power supplies is around $20.
How does electricity get from the power stations to the consumers?
Usually through cables. The power produced by the generator (typically 24KV) is stepped up to the transmission voltage (typically 138KV) using transformers. At various substations, transformers, again, step the transmission voltage down to distribution voltage (typically 13.2KV). There is another step down at the service pole, where a transformer converts the distribution voltage to service voltage (typically 120/240V or 480V three phase).
What is the need for power supplies?
A power supply is needed to transform the line voltage (e.g. 120 VAC 60 Hz, 240 VAC 50 Hz) to the voltage or voltages needed by the equipment (typically DC voltages between 3 VDC to 300 VDC) depending on the operational requirements of the equipment. Some old vacuum tube equipment needed low voltage AC to heat the vacuum tubes, the power supply then also had to provide these voltages (e.g. 6 VAC, 12 VAC). I have seen power supplies as simple as providing just one DC voltage to power supplies as complex as providing 20 to 30 different DC voltages, some positive and some negative with respect to ground.
What do power supplies do for computers?
A power supply converts line voltage (at the plug) to conditioned "direct current" voltages that are used by the CPU, disk drives and other peripherals, typically a couple 12 vdc outputs and a couple 5v and -5v outputs.
Why for an ideal power supply the output voltage is independent of the load?
Obviously, you don't want the voltage to sag. For computer power supplies, you want the power to be even, pure, and clean without any ripple.
