How much power is generated when a 9 volt battery produces a current of 5 amps?
45 Watts
Is there a battery jump starter?
The most important consideration when purchasing a jump starter is power. How much power is the jump starter getting to the battery? Many manufacturers only offer battery booster packs that have only 900 peak amps and maybe 200 cranking amps.
How much power is there in a car battery?
That will depend on the construction of the battery. Usually larger batteries have more power because they have larger lead plates inside.
When starting a motor car a current of 80 Amps is drawn from the 12 volt car battery. How much Power is dissipated in the starter motor?
12ooo
How much current does a size D battery have?
Doesn't work like that. Current drain is dependent on the (internal resistance of the battery and the) resistance/power requirements of what's connected to the battery. If shorted out, the current - unless the battery is fused or otherwise protected - can go into tens of amps.
How many watts does a 48 volt battery produce?
Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
What is the difference between cranking amps and amps?
Amps are just a general measurement of electric current in any application, whereas the term cranking amps are specific to automotive / starting battery applications. Cranking amps is a measure of the maximum current a car/ starting battery can produce in normal temperatures for 30 seconds before the battery voltage drops too much.
How long to charge a 12 volt battery at 2 amps?
It takes between 8 and 12 hours to charge a 12 volt battery at 2 amps. The actual time will depending on how much charge is in the battery initially.
Can you charge a mobile phone directly from a 12 vdc power source?
It depends on the power source - too much current (Amps) can damage the battery and/or the phone. I usually charge mine from a USB port on my computer.
Can I use a 9-Cell 11.1V 7800mAh battery for Dell inspiron 42Wh with with 11.1 Volts?
There are two general rules for connecting power providing devices (such as a battery or power adapter) to a power consuming device. The first rule is that the voltage and power types (e.g. AC or DC) must match. The second rule is that the power providing device must provide enough current (e.g. expressed in amps (A) or milli amps (1000 mA = 1A) If you can't figure out how much amps of power a device requires or consumes, you can derive that if you know the watts. current = watts (divided by) amps So your device passes the most important requirement (watts and power types match), but we don't know if your battery can provide the current your laptop needs. The problem of your question is that it is specifying the power storage capacity of your battery (mAh), not the amount of current it can transfer at once (A). So, your question is basically unanswerable.
You are replacing your Audi tt with a new battery the old battery says 280 amps the new one says 460 amps will this do any damage to your car your mates says it could blow the computer system on start?
No, your mates are wrong. The figure of Amps is the CCA or Cold Cranking Amps. Your old battery had 280 CCA and the new one has 460 CCA. Cold Cranking Amps is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. The higher the CCA rating, the greater the starting power of the battery.You are good to go, and in fact you made a wise purchase and have a much better battery now. Remember a 12 volt battery is a 12 volt battery, so rest easy, and tell your mates they know not of what they speak.
How many watts are in car bartteryes?
varies, go out and check on top of battery, should have sticker that says cold cranking amps. all batteries should run 12.6 volts, do the math from that.watts = volts * amps , take the CCA (cold Cranking amps) number on the Battery and multiply it by 12.6No one answer, as there is no one car battery. Most are 12 volt batteries, but that can really be anywhere from about 13.2 to 11 volts. A standard large battery will have ABOUT 50 amps of current. Multiplying volts times amps equals watts. 12 x50= 600 watts. HOWEVER- you cannot draw that much power for more than a few seconds. Heat buildup would damage battery.
