What is a battery unit called?
The battery has a charge unit instead of being itself a unit. A battery is not a unit. The unit for the electric charge is milliampere-hour.
Is a milliampere the same as a milliampere second?
yes
How many amps are in a 9volt battery?
It varies from one 9 volt battery model to another. The typical Alkaline 9 volt battery you find in many toys and smoke detectors has 565 mAh (Milliampere Hours) of power. A Zinc Carbon model has 400 mAh. A Lithium has 1200 mAh. There are 1,000 mili amps in 1 amp.
Which is bigger a milliampere or a microampere?
milliampere i also wondered upon this question however, it was soon explained in a lesson and months later came up in a test asking this exact question - i chose milliampere and soon founded that it was correct thanks by oxford university student
Which one is bigger ampere or milliampere?
milliampere, as with any unit with milli in front is 1000 times smaller
How many hours have for a 4400 mAh?
This is an informal unit for energy, often used for batteries. mAh = milliampere x hours. If you know how much current you will need (in milliamperes), you can divide the 4400 mAh by the amount of current, to calculate how many hours the battery will last.
How many amps does a 6 volt RV battery have?
Batteries are rated in terms of Ampere Hours or Milliampere Hours. The amount of current being delivered at any point in time is governed by Ohm's Law. Current = Voltage / Resistance.
Which lasts longer 4400mah or 4.6ah?
This refers to a battery rating (laptop in this case) Ah is ampere-hour and mAh is milliampere-hour. A milliampere-hour is one-thousandth of an ampere-hour (3.6 coulomobs) so 4400mAh would equal 4.4Ah which means it would not last as long as 4.6Ah. Thanks Wikipedia.
Which is larger ampere or milliampere?
On comparing ampere and milliampere . we can tell the relation between them as follows. 1 amp =1000000 mamp.
What is 4800mAh?
A battery rating of 4400 mAh means that the battery can nominally produce 550 mA for 8 hours. Even though it would seem that the battery will produce 4400 mA for 1 hour, it will not actually last that long. By convention, current-time ratings on batteries are normalized to an 8 hour rating.
What happens when you stick two 9 volt batteries together?
If you connect positive to positive and negative to negative you will have a 9V battery with twice the current capacity in milliampere hrs than a single batteries. The load then goes between positive and negative paralleled terminals. If you connect one negative of one battery to one positive of the other battery and put the load between the remaining negative and positive terminals you have created an 18 V battery with the same milliampere hr rating as a single battery. If you connect one negative to positive of other battery and the negative of that battery to the positive of the first battery then both batteries with quickly drain and get hot in the process. Contrary to folklore or urban lefends, they do not explode.
What is the abbreviation ma stand for?
milliampere
