Can a 9V battery power a 120V light bulb?
im not sure if this will work or not but... If you use a 9v battery threw an inverter, then a step-up transformer to convert 9v DC to 120v ac i think it will light the bulb, however current decreases when you do that and i dont know how much a light bulb needs..worth a try, i might actually try it now
Why does ammeter on battery charger read low when connected to a dead battery?
The meter shows low because when the batt. is all charged up the currant is very low because the batt. does not need to draw any more currant. When the batt. is low the batt. draws currant becaus the cells in the batt. need currant to charge.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
You just replaced your alternator on your Honda civic dx 1991 and the battery light is staying on How do you reset the battery light?
If you disconnect the battery for 20 min it should kill all memory and reset everything.If not you charge is still low charge up your batt. with a charger.and test your alt. output 13.9-13.7 you have to check the book.I'm not to sure on that.You might have a voltage regulator problem bad batt. Or somthing is hooked up wrong. Mabey the old alt was fine. Have the batt. tested. All alt. well most are rebuilts so you might have a bad one it happens.Make sure that it's putting out a charge. All the way to the batt. Good luck.
What is a dc9v on a guitar used for?
9v batteries are used to power the pick up's up guitars.
Can you operate a 120V 60 hertz tv on 120V 50 hertz?
no because the tv can only pick up siginals at 60Hz if the signal is 50 Hz it won't pic it up.
2003 Dodge van and it will not turn over?
Check spark next if cranking, if not, batt. If you have some power, but no crank, charge or jump & let alternator bring up batt level.
How do you wire 240V to 120V?
What specifically are you wiring? A light bulb would operate dim, a motor will burn up. The current increases thereby requiring larger wire and current protection.
If 227v connected to 120v ballast what happens?
The ballast burns up.
Can i get 9V to 110V transformer in the market?
Sure. You can go a couple of ways. You can look for a 110v to 9v transformer, if you can find one, or you can get a 110v to 18v center tapped transformer. If you get the second one, when you hook up the 9v side, you connect between one of the ends of the 18v coil and the center tap. Right now you're thinking, "I said a 9v to 110v transformer, not a 110v to 9v." That you did, but transformers don't care about that--they'll step voltage up as readily as they'll step it down. (Back when all we had was tubes to work with, transformers with a 6v winding and a high-voltage winding--300v, 400v, 2500v, whatever--were very common because tubes need a LOT of voltage to work.) There are two things you really should think about here if you're trying to take 9v to 110v. First, if your intention was to get line voltage out of a 9-volt battery, stop right here. Transformers only work with AC voltage, and a battery puts out DC. The other thing is, if you've got 9v AC and you feed it into a transformer that will give 1A at 9V, 0.08A at 110V will come out of the unit. Eight one-hundredths of an amp isn't really enough to do anything with. If you want to get 1A worth of 110v from 9v, you need to feed (assuming perfect efficiency in the transformer, which you will not get) 12.5A at 9v, or 25A at 9v if you have a transformer with a more likely 50 percent efficiency. It's possible to step 9v up to 110v, but it's probably not worth your time to do so.
What is the proper hookup order for a 1995 southwind 12volt battery then to two 6 volt can't remember where all the cables go?
Main Batt far left side. Positive on the left, wire goes up and across top above radiator area and up to connection. (2 wires on Negative)1 Small wire goes up and 1 hooks to frame ground along with negative of left hand 6 Volt Batt. Positive of this Batt hooks to negative of the next 6 Volt Batt. Posative hooks up to 4 wires that goes up the right side of the compartment.
Why does the panel light up on your 1992 Crown Victoria but the engine wont turn over and you dont hear a clicking sound?
its suppose to. batt. is to low, engine switch is not good if the lights do not turn off when turning the key
