I think 1 .6
No. The sizes of the batteries give indication as to how much current they can produce at that voltage.Another Answer:There is no A-cell battery. There are AA batteries packaged in a D shell. If you avoid those, a normal D-cell will deliver a lot more energy than an AA-cell, so connected to the same device/load it will last longer.
you will have to get 2 batteries and compare it
A "D-size" carbon-zinc cell at 100 mA would have about ten times as much "energy" as a 9V carbon-zinc at 8mA. A battery in the AAA series would have about the same energy as a 9V, which should not be surprising since a D is 10 time larger than a AAA.
If we assume the same battery chemistry and quality, and the same drain, then the D cell will last longer than the AAA cell, as the bigger size means it'll hold a bigger amount of energy.
Depends on whether the battery is rechargeable or not, and the battery chemistry, there are several different in the D-cell size.
A D cell battery has a voltage output of 1.5 volts, while a 9 volt battery produces about 9 volts. This is just the potential energy though. D cells provide far more current for a longer time then a 9 volt battery. In terms of overall power output, a D cell in give you many times more power than a 9 volt battery. Physical size, in this case is a good indicator as the material inside is the same.
Well, a normal battery, a car battery, I can't think of more ! ------------ All chemical substances have chemical energy.
this question is missing information and therefor makes no sense
I don't know :D
D cell battery
A D-cell is a standard 1.5 volt electrical dry battery. It may be the largest 1.5 volt cell.
Put a test meter on the end of the D-cell battery
