What devices use water to operate?
HydroElectric generators (think of Hoover Dam) , water wheel , steam engines by heating the water ,
Why do we need a transformer if we use a welding machine?
A welder requires high current at the expense of voltage, The transformer reduces the voltage allowing a higher current to operate the welsing machine.
What is the difference between electrical and mechanical devices?
Electrical degrees and mechanical degrees in dc motors are related by the equation: Deg(elec) = (Number of Poles/2) *(Deg(mech))
What size resistor to drop 3 volts to 2.4 to use an LED?
LEDS are diodes and will operate correctly only when the voltage is sufficient and also the current is sufficient. So i cannot solve it correctly since i have no info on the current. Generally a led can be safely conduct if the current is around 0.020 amps or 20ma so 3-2.4=.6v .6/.02= 30 ohms.
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.
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.
Devices which use semiconductors use current to operate than those which do not use semiconductors?
less
What kind of electricity does America use?
America uses 60 Hertz (Hz) Alternating Current (AC). Most smaller devices operate on 120 volt current.
What devices use photovoltaic panels?
Devices that use photovoltaic panels are solar panels, and power plants. They convert the suns solar energy into direct current electricity. These panels are typically made out of silicon.
Why does an LCD use AC?
Because Alternating Current is the standard form of electricity available, devices which operate on Direct Current, such as a Liquid Crystal Display, have a converter, which converts the AC into the appropriate voltage of DC.
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.
What are the other instruments or devices that use electromagnets to operate explain how they work?
give atleast 2
What kind of electric current does an electric stove use?
An electric stove uses Alternating Current to operate.
What instruments do AC to dc current use?
I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
What types of mobile devices can use Foursquare?
The current version of Foursquare can be used in all mobile devices with internet access. Earlier versions were not as advanced as the current version.
What are some devices that use the wi fi technology?
Devices that use wi-fi technology are typically mobile devices. Examples of these devices include laptops, e-readers, tablets, mobile phones and smartphones. Other devices, such as computers and televisions, may also use wi-fi technology.
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
