Yes, you can. There are numerous companies that make AC/DC power adapters. Simply type in " (TV Model and or brand) AC/DC adapter."
You can plug an AC computer into a DC plug only if you also have an inverter to transform the DC power into the AC power that the computer power supply expects.
an adapter can help in this case.
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
Only if you plug yourself in, The answer is no, nerves transmit tiny DC electrical charges.
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.
AC, when you're going to test a product which cannot tolerated the power source in your home. ex. in testing a 15A bulb, you cannot test it directy to the wall plug in your home instead you use AC tester(alternate current) to convert the supply to its limit or else it will fry your bulb. DC(direct current), when you're testing a high voltage product and it can tolerated the power source from your wall plug.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
It is not safe to plug a generator into a home outlet to use the power elsewhere. This is known as backfeeding and can lead to serious injury or death to utility workers or damage to your generator. For safe use, generators should be connected directly to the appliances or devices you want to power using appropriate extension cords.
computer, t.v , radio etc
It is dc but a small attached converter can make it ac for home use
If you are talking about the standard cigarette lighter socket in an automobile, you can only use devices that can run on 12 volts DC ((most modern cars) within the rated AMP load capacity. A standard house outlet is designed for 110 volt AC devices that have a 110 volt AC source
No. 9 v is only 75% of 12 v.
