Electricity is generated as alternating current because its voltage can be raised easily, and very efficiently, using Transformers. For a given load, the higher the voltage, the lower the resulting load current. High voltages are essential for electricity transmission and distribution in order to avoid enormous voltage drops and to allow conductors to be light enough to be strung from towers or poles. So electricity reaches your house as alternating current. Because of this, all your appliances are designed to run off a.c. or, if they must use d.c. (e.g. audio equipment, computers, etc.), then they incorporate a transformer/rectifier to change the a.c. into an appropriate value of d.c.

Is electricity AC Or DC currant which one?
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
Car electricity uses ac or DC?
DC
Which choice defines AC and DC correctly?
Choice of electricity defines ac and dc
Which device is use to convert kinetic energy into electrical energy?
Alternator = AC electricity Generator = DC electricity
What doaes ac DC stand for?
The two forms of Electricity are AC and DC. AC Stands for Alernating Current and DC stands for Direct Current. AC electricity comes out of the Powerpoint that your computer is probably using and DC electricity is used in 5.1 voltage batteries that probably power your flashlight or toy.
What types of electricity can biomass energy turn into?
AC or DC, whatever you want. It produces the same electricity that you use for your home.
Do phones use ac or dc?
Some devices operate on AC and others on DC. Generally, anything that uses mains electricity (120V US, 240V UK) is using AC electricity and things that use batteries or are rechargable like cell phones, ipods, personal CD, use DC electricity.
Does a light switch produce AC or DC electric currents?
Alternating (AC) and direct (DC) currents are different forms of electricity. It is universal nowadays to have AC in all houses because the electricity grid distribution system is all AC. DC was used by Edison and continued for some years but is now discontinued. It is still used in vehicles where 12 V DC is the normal system. A light switch simply interrupts the current or makes the circuit as required, and both AC and DC need to have switches.
How many people still use DC electricity?
If you are talking about DC power line electricity, it is no longer used in homes or industry however many electric rail systems (e.g. trolley, highspeed trains) use DC electricity as DC motors have several advantages for motive power compared to AC motors. A few very long transmission power lines use DC electricity, but the DC is converted back to AC electricity before being distributed to customers. Certain industries (e.g. electroplating, aluminum refining) use DC internally, but they use large rectifiers to convert 3-phase AC to DC electricity when it enters the plant.If you are talking about electronic equipment (e.g. radios, computers, cell phones) these usually contain batteries. Everyone using battery powered electronics (or lighting, toys, cars, UPSs, etc.) uses DC electricity, because that is the way batteries provide electricity.Nearly everyone uses DC electricity, in battery powered devices.
What supplies the energy to split Water?
You can use batteries supply DC electricity to split water to O2 and H2. Alternatively, you could use Transformerto transform AC electricity to DC current and split water.
Does Europe use AC or DC current for electricity?
Europe mostly uses 220 to 240 volts AC current at 50 Hz.
Is the electricity from batteries AC or DC?
Direct current
