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 whats 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 dont we use DC for everything...??
A friend of mine did it. He has a12 VDC light in every room and outlets for RV appliances where practical.Would it be practical to build a house with both AC wiring and a DC wiring.
Fine for LED lights, radio and TVSeems 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
High power DC circuits need special switches, fuses and breakers to operate safely. It's possible to have a DC system in a house but once you get above about 50vdc to reduce wiring sizes it becomes very important to engineer it correctly. You can't normally find the correct parts at the local big box stores so it will cost more.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.

You can use the power to heat and/or pump water. It's possible to use a preheat tank as a diversion load for solar electric systems. People take a small AC electric water heater and install a DC heating element to warm water before it goes to the main hot water heater system. It's not as efficient as direct thermal solar heating of water but if you have lots of excess power from panels it's better than nothing.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 ?
