How much voltage inside a sunbeam battery?
Automobile battery is 12 volts. If it is fully charged you should actually read 12.6 volts.
How is it possible to have a high current with a low voltage such as in a car battery if current equals Voltage divided by Reistance then shouldn't a low voltage produce a low current?
It's all relative. A battery has internal resistance. Batteries are not "ideal" voltage sources. If there is a "heavy" load on the battery (low resistance), the voltage you measure on the outside of the battery will be lower. A car battery is normally thought of as a 12 volt battery. When there is no load (disconnected) you can often measure in excess of 13 volts if it's fully charged. During normal cranking of the engine, the voltage can drop below 11 volts.
How does an alternator produce different amps?
It depends on the load and the voltage. In an automobile, a battery will typically have a voltage of about 12 Volts. If the engine is not running and you turn on the lights, the lights will start drawing current from the battery and the voltage will drop by a volt or so, depending on how strong a charge the battery has. An alternator will produce in the neighborhood of 15 Volts. If it is trying to push current into a system with a fully charged battery, it will only be able to push a few amps. If the voltage in the battery drops, the alternator will be able to push more amps. A completely dead battery will draw the most current (amps).
How can I convert a DC adapter operated device into one that uses a battery?
A: A DC adapter is basically like a battery except it is conditioned from an AC source. To change over measure the voltage when fully operational then switch to battery that have the same voltage as the adapter. the only concern should be the power required
How do you make your kindle fire come on when the green light comes on and then goes off?
are you sure you have it fully charged? (also i heard that if you buy a new electronic and you unplug it before it is fully charged it will have less full battery usage every charge, so if you unpluged it just after it started charging the first time you might have almost no battery power at full charge)
What are typical voltage for fully charged and half charged batteries?
A fully charged 12 volt automotive battery should have 12.68 volts.
Voltage reading for a fully charged Battery?
12v
What is the minimum acceptable voltage on a 12 volt battery?
Fully charged should be around 12.8
What voltage should your truck battery be at?
12 volt batteries if fully charged should show 14.2 volts
How much voltage inside a sunbeam battery?
Automobile battery is 12 volts. If it is fully charged you should actually read 12.6 volts.
What is to be done if the battery voltage check shows less than 22.5 Volts in a battery?
What voltage battery are you referring to? An automobile battery is 12 volts and a fully charged auto battery should read 12.6 volts.
What is the potential voltage of each cell in a fully charged battery?
250v On an automotive battery it is 2.2V
What is the voltage of one cell in a car battery?
2.2 v when fully charged.
What is the totally voltage of a fully charged 6 volt battery?
6.32 volts is 100 percent charged
Voltage for a fully charged car battery?
Normally in off load, its about 12.6 volts. 12.6 is correct for a fully charged battery. 12.4 it is 75% 12.2 it is 50% 12.0 it is 25%
What is voltage at battery with motorcycle running?
Typically 14 to 14.5 volts assuming a fully ( or nearly) charged battery.
Is your battery bad if the voltage reads 10.5 volts dc?
First it would depend upon the type and voltage rating of the battery. If it is a lead acid battery, I would recommend charging it to its recommended voltage and load testing it. A fully charged 12 volt automobile battery should read 12.6 volts. A battery that reads 10.5 volts is completely drained. If the battery is fully charged and only read 10.5 volts it needs to be replaced.
