Yes it is.
A computer operates by working with pulses of electrical energy. Depending on the voltage of the pulse, it represents either a zero or a one. Electricity is also need to spin the disc drives.
electricity gives display to the computer
Energy conversion in computer is the process in which energy surplied to computer is being converted for computer use, is AC 2 DC
BUS
A rectifier is a device that converts AC to DC.A transformer is a device that changes the ratio of current to voltage.A computer power supply functions as both.Answer found in CompTIA A+ Guide to Managing and maintaining Your PC 6th edition on page 154.
the power supply
The energy used to power a computer is Electrical Energy.
A computer operates by working with pulses of electrical energy. Depending on the voltage of the pulse, it represents either a zero or a one. Electricity is also need to spin the disc drives.
Your computer screen uses the same type of energy as any other electronic appliance: electricity.
The thermostat regulates the temperature in the home.
The wattage rating tells you how much electricity its consuming, most electrical appliances give this information.
Yes, the phenomena of electricity are studied by the science of physics.The phenomena of electricity are used in the engineering fields of electrical engineering and electronics engineering. One branch of electronics engineering (computer engineering) was used to design the computer you are now using to read this.
No because the current rating of the transformer is a maximum allowable current. If the computer still takes 3.42 amps it will be OK provided the new transformer supplies the correct voltage.
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.
While it's hard to define one "most important" part, I'd have to say that the power supply should have that distinction. Without electricity flowing to the computer, the rest of the electrical system has no purpose.
No, the energy that powers a computer is electrical energy. Chemical energy is energy that is stored in the bonds of molecules. Batteries, candles, matches and food are some things that have chemical energy. When the molecules/compounds' bonds are broken, the chemical energy is released. In a candle, this would cause a small fire. Electrical energy is the movement of electrons. The electrons move quickly inside the wire, & power the computer as electricity.
Considering your body is run on electrical impulses, you use it all day every day.
