Cell phone battery voltages?
Cell phone voltages are DC5V-5.5V
What is an electrical battery?
It is a storage device for D.C. voltages.
How many volts is in a battery?
Batteries come with different voltages.
How many batteries will it take to make 120 volts?
It depends on the terminal voltage of the batteries, as different types of battery (or, more accurately, 'cell') have different terminal voltages. A car battery has Approx 12 V, so ten of them.
Can you have batteries of different voltages?
Yes. The voltage is determined by the chemistry inside the battery.
Can rechargeable batteries be charged by a car battery charger?
It's a good idea to avoid charging any battery with a charger that was not designed specifically for that kind of battery. A car (vehicle) charger is generally designed to recharge 12 volt lead acid batteries. (The actual voltage of the battery and charge is a bit higher than 12 volts.) Rechargable battery packs come in different voltages, and many if not most are not lead acid types. A lot are nickel-cadmium or lithium types, and they need a "controlled charge" that a vehicular battery charger will not be able to provide. And that's setting aside the issue of the voltages of the battery and the charger, which is critical.It's a bad idea to attempt to recharge a battery with a charger that is not designed to recharge that "flavor" of energy storage device.
Can you describe how batteries are sources of voltage?
The number of cells in a battery determine the battery's voltage. Different types of batteries have different cell voltages. The cell voltage is dependant on the reactive metals used. A typical car battery will have six cells. Because a typical cell voltage has a source voltage of approximately 2.0 volts, this makes a car battery produce a voltage of 12 volts.
What is the Makita Battery Charger used for?
The Makita Battery Charger is used for Makita batteries. This battery charger is capable of charging many batteries depending on the voltages for the batteries.
What meant by one terminal of a car battery said to be connected to ground since it is not really connected to the ground?
'Ground' is an electrical term indicating the return path completing a circuit . ~ See related link below . The negative terminal of a car battery is connected to the chassis of the car. This defines the reference point for measuring voltages in the car. It is possible for the body of the car to be connected to the ground, such as when the car is put on a metal jack. This has no electrical effect, so the body of the car is pretty much equivalent to ground.
What are two differences between a car battery and a flashlight battery?
there are lots more amps in a car battery eg there about 1.5 in a flash light and in a car battery there about 300 A car battery is a wet cell battery and a flashlight battery is a dry cell battery.
Does a car battery have mercury in it?
No, a car battery does not have mercury in it. It would be very dangerous to have mercury in a car battery.
How the voltage is being stepped up in the case of mobile chargers?
If,for example, a 12 volt car battery is used to charge an 18volt mobile battery then an electronic oscillator stacking voltages on capacitors via diodes is used. This is called a 'charge pump' or 'Cockcroft and Walton' voltage multiplier.
