I wonder if AC current follows Sin wave and go through negative and positive cycles alternately, why don't AC equipments, like a bulb, get off and on - off and on...
In principle that could produce a stroboscopic effect.Hmm...but what's with waving pen in air...?
Biggest problem with DC (especially in the past) is stepping it up to higher voltage. HV is necessary for a long distance transmission.And what is the point of having AC in the first place? Why don't we use DC for everything...??
Try it.Hmm...but what's with waving pen in air...?
Would it be practical to build a house with both AC wiring and a DC wiring.
Seems like a large portion of consumer electronics switch the AC to DC anyways and if we can skip a conversion step or 2 there might be efficiencies to be had
I recently had a discussion with someone around renewable energy sources and their drawbacks.
On the topic of solar power, I mentioned the issues around converting the DC solarpower into AC in the grid and started to wonder. Would it be practical to build a house with both AC wiring and a DC wiring.
That way you have the solar panels supplying the DC lines, with some method to "top up" the power req's from the AC lines if needed.

I hav a question if we can use a sola panel as a power source is the eny thing that we can use to store the energy from the sun rather than using battry bank's ?
If only there were a very efficient and cheap way of storing Electrical Energy directly. The only way to make use of the large amounts of relative cheap energy that can be generated off-peak, is to use pump storage (electric pumps to take water into a high reservoir and then hydroelectric generators to provide the electricity when needed). It's inconvenient, not very efficient and you need some mountains with valleys fairly close to your power stations and city.I hav a question if we can use a sola panel as a power source is the eny thing that we can use to store the energy from the sun rather than using battry bank's ?
