No, it is better to replace your thermostat with a programmable one. You can typically save 10-15% on your bill by using a setback. It is an easy diy project.
leave it open all year closing it during the day open at night for ac
A dc welder is a lot cheaper by fair of the two
the paint is cheaper
The main target of AC AND DC IS TO GIVE SUUPLY TO CONUMERS WERE AS AC CURRENT IS CHEAPER COMPARING WITH DC
I Think you,ll have to expand your question , what do you exactly mean by "cheaper"
It really is not safe to leave a AC adapter plugged in. If not using I would unplug it.
AC is easier and cheaper to send from the generators to the consumers than DC is.
Only when your car engin runs.
ac transmission is better. because it is cheaper as converter are not use.but losses are more as comparison to dc.
It produces alternating current AC. It is cheaper to build than a DC or an AC - DC welder. Most electrodes can be used with DC. Some can be used for both. Very few are AC only. DC produces a smoother arc, is easier to strike an arc and most machines in industry are DC. Surprisingly a lot of AC machines are on farms as they were cheaper to buy.
