Yes. In almost all cases, the current follows the voltage waveform.
The peak amplitude of the current depends on the device or appliance
that's drawing the current.
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
because in dc current is direct current and it continously varies. so it may be possible that some instrument may be damaged. so to avoid this first we have to convert dc to ac. Actually in our home dc is provided.suppose you want to charge your mobile than you have to convert first dc current to ac current.AnswerAll homes are supplied with AC voltage. The reason for this is that the magnitude of an AC voltage is easily changed using a transformer, and it is easily changed into DC using a rectifier. Changing the voltage level of DC is far more complicated, as is changing it to AC.
At the typical U.S. home, the voltage at the wall outlet is somewhere between 110 and 120 Volts AC. Most U.S. homes also have 220 Volts (which is actually somewhere between 220 and 240 VAC) available, but not wired to most rooms.
Because higher voltage can carry further. That answer is too simplistic. The actual reason is as follows: for any given load, the higher the supply voltage, the lower the resulting current. Lower currents mean smaller diameter transmission/distribution conductors can be used and the line losses(I2R) are lower.
we will get rectified voltage at the output.in case we replaced the DC source with AC source
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
It needs to go to all the homes and increases current i dont know if thats right its just a guess.
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.

Yes, using a 220v-60hz microwave in Australia is fine. The voltage of alternating current supplied to homes in Australia is 220v. The frequency of the voltage is 50hz.
Solar photo-voltaic cells produce dc current at a low voltage, so it is not directly usable in homes or factories. Cells may be placed in series to increase the voltage, but the current must be turned into ac using inverters, and the voltage transformed up to what the distribution system requires. Unless the installation is feeding an isolated home or homes without a main supply system, the power will simply enter the distribution system, and the user won't know any difference.
Oh, dude, that force you're talking about is voltage. It's like the push that gets electricity flowing in your home. And yeah, in most homes, that push is around 110 volts. So, next time you plug in your toaster, just remember it's all about that voltage making things happen.
The electric current supplied to most homes is alternating current (AC).
The "force" that pushes an electrical current is the voltage. It isn't really a force, but it may help to visualize it as such. Physically, it has different units than a force.
The power transmission would require bigger wires to transmit high dc current so instead high voltage ac current is transmitted through long distance linesTo reduce losses it is necessary for the value of current through lines to be lowTranformers donot work for dc current so one cant step up and step down dc current voltage like it can be done with ac current
230 volts
When you run wires past a magnetic field you generate electrical current . The number and length's of wire wrapped around a shaft of a generator help determine the voltage moving voltage oscillating back and forth is called alternating current and the current flow or pulse is measured In hurts which is a function of how fast the field winding wires on a generator are turned and from what i understand our power companies generate 3 phase power and we only use one leg of that power for our homes electricity and the have to balance the other legs of those wires with other power needs and commercial power uses all 3 phases to there building's as opposed to our split leg 220 oar our single phase 120 voltage. wattage is volts times amps which is the measure of electricity
