Why are Power supplys for laptops 19v instead of 12v?
This is due to the fact that the Li-ion needs to be charged while the computer is running. The charger will input a higher voltage to charge the battery while the 19v is pushed through a buck converter on the motherboard that outputs a regulated 12v to power the motherboard. This is neccessary to efficiently charge you laptop battery.
Why does a computer need a battery?
CMOS battery of your laptop maintains hard disk, time and date, and other drivers and configuration settings in a CMOS memory. You will see these tiny CMOS batteries connected directly to the laptop’s motherboard.
How are the solar powered car and the electric alike and how are they different?
Solar powered cars have a solar panel somewhere on the outside of the car, and the energy is either directly run to the wheels, or charges a battery, which then powers the wheels, where as electric powered cars use only a battery, which can now be charged using a regular plug.
What does the H and S stand for in HS Battery 3rd Gun Battalion 38th Artillery?
What Country and Time period?? Assuming this is US during WW2, then the "HS Battery" is probably "HQ Battery". The typical Field Artillery Battalion contained three firing batteries named "Battery A", "Battery B" and "Battery C" and a smaller service battery called "Service Battery". The Commander, his staff and clerical assistants were part of the "Headquarters Battery" or "HQ Battery". If your question relates to a different country or period, then the HQ Battery and Service Battery may be combined and called "H&S Battery" but I'm not sure of that.
What is the meaning of the battery symbol on electronic devices?
The battery symbol on electronic devices represents the power level or status of the device's battery. It indicates how much charge is left in the battery and when it needs to be recharged.
What is an AC to DC converter called?
While 'rectifier' is the component which converts AC to DC, the entire converter unit which converts AC to DC is also known by the name 'Eliminator'.This, as the old timers will tell you, is short for 'Battery Eliminator', as quite often, the AC-DC converter is used as a substitute for having to use the batteries. It allows the battery driven equipment to be powered from the mains directly.
Will catalytic converter affect battery power?
No.
What energy transferred to one coulomb of charge within the battery is called?
The energy transferred to one coulomb of charge within a battery is called electromotive force (emf).
Can we charge a phone with dc current?
Your mobile phone charger already have ac to dc converter , as ac supply can't stored. and you can charge directly with dc supply by maintaing volage of battery and dc source.
How does energy get transferred into a battery?
Energy is produced in batteries due to chemical reaction.
What electricity will let battery and light bulb flow?
Direct current (DC) electricity is the type of electricity that will flow from a battery to power a light bulb since batteries provide DC power. Alternating current (AC) electricity, found in most wall outlets, typically can't directly power a light bulb from a battery without a converter or inverter.

What can heat energy travel through?
Heat energy can travel through solids, liquids, and gases. This means that heat can be conducted through materials like metals, transmitted through fluids like water, and even transferred through the movement of air or other gases.
The potential difference supplied by the battery is 4.5 VCalculate the total energy transferred in 300s?
energy transferred = charge x potential difference.
How to run an ac current sawzall on a car battery?
you need a converter a fairly large one
Can a 120vac refrigerator operate from a 12vdc 10a converter?
Absolutely not. I think it is possible, but it depends on how many Amps [or Watts] the refrigerator draws [uses], AND the sustained output [Amps or Watts] that the converter is capable of producing. For example, if the converter was rated for a sustained/continuous output of 10 Amps at 120 Volts [that's 1200 Watts], and the refrigerator requires only 6 Amps at 120 Volts [that's 720 Watts], then I say the converter can safely operate the refrigerator.Answer 3 -- Watt?Are you thinking of running a 120 volt refrigerator from a car battery? Back up to "absolutely not". There are RV refrigerators that can run for a short time from a car battery (preferably a deep-cycle type), but they can barely keep the fridge cool under the best of circumstances.Unless the engine is running, the battery will be drained in a couple of hours. If the battery is a deep-cycle, you can recharge it; if not, you'll have to buy a new battery.Also, if the fridge requires 720 watts and the converter is only 50% efficient, it's sucking 1500 watts from the battery, which is a lot more than leaving the headlights on. Even the little "six pack" coolers that run on 12 volts will run a battery down pretty quickly unless the engine is running. Try using an ice chest.
How do you find battery terminals for a 2002 Dodge Stratus?
On the top of the battery look in the engine compartment directly above the battery.
