In short - No.
Batteries by themselves don't produce any power at all.
And "power" is rarely used in relation to batteries. It's far more common to talk about "capacity"(amp hours) than "power"(watts)
To get a power output you need to hook something up to the batteries, and generally speaking it's this hooked up thing - the consumer - where it makes sense to talk about power.
Electrical power - watts - is calculated through current(amps) x tension(volts)
Different batteries have different discharge characteristics - that is - which voltage they can maintain at a certain current drain. So the amount of power being delivered will depend on how the battery will react to what the consumer is trying to draw from it.
There are batteries which do well at high-discharge rates, which I guess could be seen as "high power" units. But again, it isn't the usual way of describing things. A high-discharge battery can release more power(watts) than a regular battery - but only if the consumer allows it.
yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high resistance.
no..... The battery with lower voltage will consume power from the higher one...
Yes and no. Some high power ham radios do not run on batteries, but use 12 volt power supplies. You can hook this up to a car battery and use that, but a higher power radio will exhaust its power quickly, so it is impractical. Smaller, handheld radios do run on batteries, and put out a lower power signal.
Does the lower the AM radio frequency number goes require night power to be lower or higher?
higher
higher
I think they have Photovoltic cells that produce a DC current from sun light to charge batteries, then the batteries power an electric motor that turns the wheels to power the vehicle.
Yes many lower level batteries actually use the common light to power themselves
The electric energy in a portable stereo is in the batteries. The batteries are what supplies the power to the stereo and in turn makes it work and produce the sound.
9V batteries are a type of alkaline battery. The alternative is a lithium battery. Alkaline batteries use zinc as an anode whereas lithium batteries use lithium. Lithium batteries produce higher voltage and have a longer lifespan, thus they are more expensive.
Because it is much more efficient to transfer power over a long distance at a high voltage. The higher the voltage the lower the current (amps) and heating losses in the line are proportional to amps2, so the lower the current the better
