Sorry still not sure how to calculate all this power stuff, if you could help with that part too id appreciate it
When looking at batteries you want to know how many amps they can supply for how many hours.
Lets see if I can get this right;Power is measured in joules (J).But obvioulsy you can apply power over a long time or over a short time.Energy is measured in watts (W).A watt is a joule/s i.e. it is a measure of how fast power is being supplied.
Power is the rate of energy delivery. Power is measured in watts, energy in Joules.
