What are Electrical devices are rated in according to the amount of energy per second that they need to operate?
watts
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.
Why low power VLSI technology is preferredover VLSI technology?
Low power VLSI is preferred over VLSI.It is because of the following reasonsIt consumes less power i. e. the power consumption is lowThe power dissipation is also lowmost of the modern devices need to operate at low powerComplex systems can be designed with reliability as the power consumption is low.We use modern electronic devices like mobiles ans robotics. These are generally compact and movable. Hence, they operate with a battery rather than power connection. Hence, we need low power operation.
Why do we need DC power supply for electronic devices?
Most active electronic devices (devices that amplify or switch states, e.g. vacuum tubes, transistors) only operate when conducting in one direction. If the current reversed periodically (as it does in AC) these devices would either not work at those times or would do something much different than they were designed to do. Thus DC is needed to keep them operating all the time.
Devices that use semiconductors to produce electricity from solar energy are?
Photovoltaic cells
Devices which use semiconductors use current to operate than those which do not use semiconductors?
less
What devices use lasers?
There are a great many devices in the world that use lasers. Computer mice for example might use lasers to operate efficiently.
Do devices operate on power or current?
Electrical devices use power to operate, but power does not exist without current. Alternately, if current is flowing, power is being stored or used by some electrical device.
What are the other instruments or devices that use electromagnets to operate explain how they work?
give atleast 2
What are 3 devices you see or use everyday that make use of the relationship between electricity and magnetism to operate?
speakers, microphones and electric motors
Could you use a Blue tooth device and send it to a Infrared device?
No. Bluetooth and infrared devices operate on separate frequencies.
Do dual band routers allow g WiFi to operate at g speeds and n to operate at n speeds simultaneously?
A dual band router will allow 802.11g devices to operate on the 2.4 GHz band while allowing 802.11n devices to operate at their maximum speed on the 5GHz band. Both the G and N devices will be able to operate simultaneously.
What is sofware?
Software is the programs that are used by a computer. The computer user is able to use a variety of software to operate the computer or other devices that use software.
What parts of a robot allows it to move?
Automation engineers use electric motors, hydraulic and/or pneumatic devices and solenoids to operate their designs.
Switch and a router are they like devices?
Yes, they are devices that operate at different layers of the OSI model for networking.
What layer of OSI model is multipurpose devices on?
If devices are within the same network then they operate at the second layer.
Which hardware devices can operate at any layer of the OSI model?
Gateway
