What is voltage divider circuit?
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
What is the total voltage if 12v 6v and 2.5v batteries are connected in parallel?
Don't try it in real life -- the batteries will become extremely hot and catch fire. Theoretically, the circuit is not allowed -- fundamentally impossible. Each battery can be thought of as a voltage source in series with a variable resistance (the internal resistance of the battery). If you connect these in parallel, the 12 volt battery will attempt to bring the parallel voltage up to 12 volts. To do so, it will push current out to the other two batteries. The other two batteries will supply their respective voltage to try to counteract this. They will begin to heat up; As the 12 volt battery supplies current above what it is designed to provide, its' internal resistance will increase, causing an increased voltage drop inside the battery (causing more heating in the 12 volt battery), which causes the 12 volts it is trying to push out to drop to closer to the other batteries voltages. the 2.5 and 6 volt batteries' internal resistances will also increase as they accept the current from the 12 volt battery, allowing the parallel voltage to increase to closer to what the 12 volt battery wants. This will continue until only one battery survives, most likely.
How do you fix your computer when its needs a new voltage battery but when it is replaced the computer still won't turn on?
you would probably assume the battery wasnt the problem. Ask yourself what made you so certain the battery was the problem.
How does the potential difference across the light when batteries are added in series compare to parallel?
When the batteries are connected in parralell, the voltage remains the same as a single battery, but the current capability is doubled. When connected in series, the voltage doubles at the light, but the current remains the same as if a single battery was connected. Ohm's Law E=IxR R=E divided by I I=E divided by R E=Voltage R=Resistance I=Current
How do you test a John Deere alternator to see if it is putting out a charge while still mounted?
Your 12 volt battery should be about 12.5 volts without the engine running. Test and verify it is. Now with the engine running test again, Voltage should now be around 13 to 14 volts. If not, then your battery or alternator are bad. To check a battery try charging it with a battery charger.
Can a lr44 battery be used in place of a Cr2032 battery?
cr2032 same as lr44?
Anothe Name for the LR44 Battery?
Many times batteries are the same but come in a variety of different names or number combinations. A lot of times this has to do with which company manufactured the battery. The LR44 battery is no exception. Another very common name for this small watch battery is the 357. The circumference and voltage are the same; the only difference between the LR44 and the 357 batteries is the name.
What does the H mean on an LR44H battery?
LR44H is equivalent to LR44.
What size of battery does a hex bug nano need?
ag13/lr44/a76
What is the battery equivalent of LR41?
Different companies have their own numbers for the same size battery. So LR44 is sometimes SR44 I hold here a DuraCell pack of LR44 and on the packet it reads also: A76 KA76 V13GA 1.5V Alkaline
Where would be the cheapest place to buy AG13 or LR44 batteries?
I kno one place would be walgreens, that were i got my battery's for about $4.00 - $5.00 and for two of the same battery in the one pack
A battery produces voltage using?
battery produces voltage by
Why is the measured voltage of a battery not the same as the stated voltage?
The measured voltage of a battery may not match the stated voltage due to internal resistance, temperature, or the age and condition of the battery. These factors can lead to voltage drops when the battery is in use.
What ars the battery needs for a crosman 420 laser sight?
3 LR44 or 3 357 Ray-o-vac or 3 D357 Duracell
Does higher voltage mean longer battery life?
Yes The larger the battery, the more voltage the battery has.
Difference between 357 and 357A button battery?
The 357 (ENERGIZER 357/303H) is a silver oxide battery with a relatively constant voltage during its life until the voltage drops off sharply when it dies. A standard replacement is SR44. The 357A is an alkaline battery the voltage of which drops slowly and constantly during its life. There are also silver oxide versions of this cell (ENERGIZER 357/303) with similar voltage characteristics. A standard replacement is the LR44. Practically, if your device is more demanding of its battery (for example, fancy calculators and measuring devices), use the 357, if it is less demending, you can use the 357A. If you try a 357A, and your device doesn't run very long on it, then it is more demanding, and you should switch to the 357 next time you get new batteries.
Does a 9 volt battery has more voltage than a d battery?
yes more voltage
