What provides greater power to the Bus Firewire or USB?
FireWire generally supplies more voltage, at a maximum of 30 volts. USB provides a maximum of 5 volts.
What is usb bus power?
The Voltage at which the USB Drive works at.
USB 2.0 is how many times faster than USB 1.1?
usb 2.0 is about 40 times faster than usb 1.1
When a battery does 24j of work on 10c charge the voltage it supplies is?
voltage=joule/coulomb or voltage=24/10. the answer is 2.4V
How much voltage can a USB port on a PC typically supply?
5v
What is the voltage that supplies a motor starter called?
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
What is the voltage of a USB?
Clients have to accept 4.75 to 5.25V and must be able to send configuration data as low as 4.4V. Hubs are allowed to drop as much as 0.35V. By itself, a USB plug does not have to supply more than 100mA; however up to 500mA can be negotiated between device and host. Some USB hosts simply offer up 500mA from the get-go. USB power supplies short the two data lines (white and green) which allows the device to probe for the fact that they're power supplies (i.e. that they provide the full 500mA without negotiation and that they won't respond to data).
At what voltage does a USB host supply power to the USB bus?
Pin 1 is 5 volts DC Pin 4 is ground.
What happen to the output voltage of the DC power supply if turn ratio in the secondary winding are reduce?
For linear supplies, the straightforward answer is: THE VOLTAGE GOES DOWN. For regulated unipolar switching supplies (all bets are off), it is likely that your pulse width will increase until you are at the regulated voltage set at the chip. Not all DC supplies behave the same way.
What is Hyacinth Technology?
Hyacinth Technology makes high voltage power supplies.
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.
Is there any way to control the voltage output on usb?
The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it. The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.
