That amount is always less than the energy you put into the system.
Divide the amount of useful energy you get from a system by the amount
of energy you put into it, and you find the system's 'efficiency'.

What is clamping voltage?
The maximum amount of voltage that a surge protector will allow through itself before it will suppress the power surge. When the device reaches its clamping voltage, it blocks any further current from flowing through the device and into a computer system or other electronic device.

What does the power of a machine tell you?
How fast work happens or how quickly energy is transferred.
A device that is twice as powerful as another can do the same amount of work in?
Half The time. In Physiology power is the amount of work done per unit of time, obviously you are a student so think kid.
Why is solar power a better choice?
It is not currently a valid source on earth. The cost, in terms of power to create a panel, is more then the expected power derived over their short lifespans. They produce no real power as of yet. Solar panels are fine for remote power or for backup, but are far from green due to their power to create verses power derived.
Difine bus powered devices in usb system?
A device which gets its electrical power from the Universal Serial Bus. A USB port should be capable of powering small devices.
A device or circuit that provides power to the rest of the circuit or system is called what?
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
Which wireless headphones consume the least amount of power?
Most headphones draw the exact same amount of power from your audio device.
What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
What is the name of energy amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
Is there a device where you could send an amount of electricity to different places and increase the power being sent?
electric generator is a device which can send amount of electricity to different places
What is a device or current that provides power to the rest of the circuit or system?
The Source.
Does the power consumption vary for a device depending if it is connected to 208v or 230v?
no it does not in a way it does it depends on the device and how it is setup. Most today devices need diffrent amount of power for what they are doing if at one moment a device is needing only 12V to operate but the next minute it may need 208V just an example it depends if they device can control the amount of power it consumes however if the device is capaple and wants to use 230V then it will.
How wind energy produces electricity?
The wind produces energy by pushing against a fan. The fan operates a power making device ( generator, turbine) to produce the electricity. The amount of wind can make more or less power from the system.
Is The USB port can supply power for device?
Yes, a USB port can supply a small amount of power for attached devices.
What is a power rating?
A power rating is the amount of power a device consumes when operating at full capacity. Typical power ratings of ATX power supplies are 350W, 400W and 500W.
