Does higher voltage mean longer battery life?
Yes The larger the battery, the more voltage the battery has.
Can the terminal voltage of a battery be larger than its emf?
the voltage of a battery could be larger than the emf if you are to charge the battery, in that case V=E+Ir .
Does a bigger sized battery have a greater voltage?
A larger voltage rating: yes, of course. A larger size rating: these are not normally related to the voltage rating, which is separate. A larger physical size: normally this means a greater voltage, but again, they are not directly related to the voltage rating. Size has nothing to do with voltage. Battery voltage is controlled by the number of cells in the battery. Plate size affects current delivery.
What size batteries does a fossil jr7978 use?
The Fossil JR7978 takes two button cell batteries. The larger battery is LR41 and its a smaller battery 377. To my understanding the larger battery is for the time and the smaller battery is what powers the dial display.
Does a D cell battery have more voltage than an A cell battery?
this question is missing information and therefor makes no sense
What size battery use an average flashlight?
The popular battery type are AA, 18650, AAA, 14500, CR123A, etc.
Can you use a 1400mAh battery in a camera for 760mAh?
The rating mAh is a measure of the amount of energy that can be stored in a battery. The higher the number, the more energy can be stored. Assuming that the batteries are the same physical size and have the same nominal voltage, there is no reason why a 1400mAh battery shouldn't be used in place of a 760mAh. The only difference is that the larger battery will last longer between charges than the smaller one.
Can a 0.9V 400MA solar panel be used to charge 2 AA batteries?
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
Why is a 9v battery smaller than a 6v?
It really boils down to the amount of power that the battery can 'store'. Smaller batteries are convenient but actually store less power than the larger, bulkier batteries do. Since POWER = VOLTAGE x AMPERAGE and the overall power is less in the higher voltage battery, then, it must mean that the amperage, or current available in the 9 v battery is less in the long run than the 6 v battery. For instance, an automobile battery is 12 v and has to pack quite a wallop to get a car started, yet there are much smaller 12 v batteries but they'd never be able to generate enough amperage to start the car.
Where is the voltage regulator located on an 1985 B250 Van?
It's mounted to the firewall. It should say "Electronic" in larger letters and "Voltage Regulator" in smaller letters.
How does a flashlight help one to see at night?
the flashlight causes objects to appear larger and easier to see.
What happens if you use different mAh batteries in electronics?
The battery with the larger mAh rating will last longer that the battery with the smaller mAh number will last in the same application.
