Some home appliances, specifically, resistive loads such as toasters, irons, and the resistive portions of ranges, will work on AC or DC. Motors, such as timers, blowers in dryers, or rotary sources in washers, require AC. In general, home power is AC, so home appliances should be assumed to be AC, not DC, unless you have a special case home, such as a solar powered home, running on DC.
bcoz it is costly to develop ac...and dc can be store nor ac
Because some appliances work with ac current and some with dc current.
in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.
I assume you mean : will AC wiring carry DC, and the answer is yes. But many appliances require AC to work.
this is because ac appliances need regular reversal in magnitude and direction whereas dc need a regular supply.. so no output will be produced when using ac.. that's why we use dc appliances!!!!
Anything with a transformer in it will not work on DC because the transformer will draw enough current to blow the fuse (or catch fire) because transformers must always have a changing voltage. A simple heater will work on AC or DC. Appliances with most types of motor will only work on AC.
kettles generally run on alternating current (AC) as do most household appliances. although the heating element can run on either alternating or direct current (ac or dc) as long as the voltage is the same. for example if you were to plug your kettle into your car battery it wouldn't do very much if anything. however if you were to wire ten car batteries in series ( thus creating 120 volts dc) the kettle would heat up as it normally would.
A dc series motor can work on dc and ac because dc motors are totally reversible.
Usually nothing good will happen. The appliance may not work or be damaged or overheat. Sometimes for small electronics, it will work fine. Many electronic devices have a rectifier that converts AC to DC, and DC will pass through and work fine. But other devices have transformers that will not work with DC input.
No ... AC means Alternating Current - DC means Direct Current. DC is used mostly for electronics and for voltages within our vehicles. AC is used for motors and for our household appliances and lamps.
is this an espresso maker for a car? if so its a pretty large heating element and will need 12v at about 30A it doesnt matter if its dc or ac to power the heater the ac espresso makers are around 1000w and will make more faster heating appliances need lots of power and dont care about ac or dc its easier to get one in the correct voltage
Mainly because your home is supplied with a.c. not d.c. Even those appliances (audio systems, etc.) that require d.c. supplies can be connected to an a.c. supply, because they have internal transformers/rectifiers which change the a.c. voltage to the required d.c. voltage.
