What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?
A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.Another answerThe secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.
150 volts is what percent of 120 volts?
150 / 120 = 1.251.25 x 100 = 125answer:125%150 volts is 125 percent of 120 volts.
A power supply receives what type of power?
It depends on the type of power supply. A power supply used in a desktop computer is generally supplied with AC (Alternating Current) and produces several levels of regulated DC (Direct Current) voltages required by the electronic circuits.
Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
What gives power to the computer?
Electricicity, a power source, a plug
A power supply receives 120 volts of power from a wall outlet and converts it to?
A power supply receives 120 volts of power from a wall outlet and converts it to a lower voltage output suitable for electronic devices. The conversion process typically involves transforming the voltage using transformers and regulating it with circuits to provide a stable power source for the connected devices.
What are the electrical requirements for a machine that operates on 120/240v 3 phase power?
A machine that operates on 120/240v 3 phase power requires a power source that can provide both 120 volts and 240 volts of electricity in a three-phase configuration. This means the machine needs a power supply that can deliver three separate electrical currents, each at 120 volts and 240 volts, to operate effectively.
What is the resistance of a 120-W incandescent lamp connected to a 120-V power supply?
The resistance of the lamp can be calculated using the formula: Resistance = (Voltage)^2 / Power. Plugging in the values gives: Resistance = (120 V)^2 / 120 W = 120 ohms. So, the resistance of the 120-W incandescent lamp connected to a 120-V power supply is 120 ohms.
Can a 780 watt uninterruptible power supply handle a 12.5 amp pump motor at 120 volts?
Volts * Amps = Watts 120 Volts * 12.5 Amps = 1500 Watts Doesn't sound like a good idea.
What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?
A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.Another answerThe secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.
Will a switching power supply work on 277 volts?
Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.
What kind of power does a power supply receive from a wall outlet?
Household electricity is supplied to a pc's power supply module as alternating current (ac).The power supply converts it into direct current (dc) at various voltages - such as +12V , +5V, etc. - which are then delivered to the pc's subsystems.Some power supplies operate on 120 volts 60 Hz ac but others operate on 230 volts 50 Hz ac.Which voltage your power supply uses depends on which country you are in.For more information see the answers to the Related Questions shown below.
Can you use 240 volts with a 120 volt supply?
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.
Does a power supply receive 120 volts?
The voltage your computer's power supply receives depends mainly on the standard electrical service delivered into homes, offices and factories by the national electrical grid in your country.Just a few examples: if you live in North America, that voltage is 120 volts but, if you live in, say, Europe or Australia, that voltage is 230 volts.More detailsThe voltages a power supply was designed to use depends on how old it is. Early power supplies were designed to use only one voltage: the standard voltage of the electrical service delivered by a country's national electrical grid for use by small appliances in homes, offices and factories .Since the invention of the personal computer most standard power supplies have been designed to operate on a wide range of voltages. (Such as from 100 volts to 250 volts.)
How much power flows through a circuit with 1 amp and 120 volts?
The power flowing through the circuit can be calculated using the formula P = I * V, where P is power, I is current, and V is voltage. In this case, P = 1 amp * 120 volts = 120 watts. Therefore, 120 watts of power flows through the circuit.
How many volts in a standard household outlet?
In the US a general purpose receptacle outlet would be 120 volts; England 240 volts, France 115 volts, Libya 127 volts, Okinawa 100 volts, Tanzania 230 volts . . .; all depends on where your house is.
What does 120 277v mean?
120 277V means that the electrical system is designed to handle both 120 volts and 277 volts. This is common in commercial and industrial settings where different voltage levels may be required for various equipment and lighting fixtures. It allows for flexibility in power supply options.
