What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
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.
Would cause a meter to read negative voltage across a dc motor?
A DC motor generates power when it is rotating even when no supply is connected.
Can you use a step up transformer to power your house if you use a sepereate electrical box for it?
Why would you want to do that -where would you obtain a lower voltage supply suitable for supplying a residence.
What crrent does a 203-ohm resistor draw from a 115 V power supply?
Ohm's law: current equals voltage divided by resistance, so a 203 ohm resistor would draw 0.57 amperes from a 115 volt power supply.
How is the voltage of the power supply for a series circuit calculated?
The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.
What cause excessive ripple voltage from a power supply.?
I think the cause of ripple voltage would be from a bad ground or capacitve voltage.
How much does a power supply unit cost?
Computer power supplies will vary depending on the voltage needs of your computer. A general rule is the more components a computer has, the larger power supply it will require and the costlier the supply. Average prices range from $50 to $300.
What voltage does the power supply uses in US?
Input would be 120v at 60hz. Standard US wall power.
What voltage would you expect to measure on a red wire from a power supply?
+5 VDC(Volts Direct Current)
How you amplify the current from 5 amp to 10 amp on 12 v Dc supply?
The amperage rating of the transformer in a 12V power supply cannot be changed. The size of the copper windings determine the power load (amps) it can handle and the point where the lead is tapped off of the windings determine the voltage. The only way to increase the amperage would be to tap closer to the core which would lower the voltage.If you need more amps you have to have a heavier transformer.
What is fuction of power supply?
The power supply makes the computer run, without any type of power supply it would be impossible to run a computer. The mains power supply for a laptop and the power supply unit of a desk top, both convert the high AC voltage from the mains power and convert it to low voltage DC, for the electronics of a computer to use.
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
What kind of wattage does a Dell Professional Series power supply use?
There is a 750 watt power supply and an 850 watt power supply. Both have gotten excellent customer ratings at various websites. I would check the specification compliance and voltage/frequency requirements that came with your device.
How much amp is needed for a 40 watt light bulb?
If that's a continuous load of 40 watts, you need quite a large battery, depending on how long the demand is. Car batteries supply more than 40 watts when running the cars lights when the car's ignition is switched off, so I guess something like a motorcycle battery would suffice.

Why does an amplifier need a power supply?
The power supply in either a guitar amplifier or in a professional sound amp reduces the 110v alternating current to a direct current. Also it reduces the voltage that can be used by the speakers, usually 12+ volts. Also if there where no power supply and there could be a possible way of reducing the voltage that could be used in the same was a direct current, you would here a constant phasing type noise from the current alternating. A power supply unit converts power that can be used in correctly in sound frequencies.
