I have three questions:
1) How one can determine the amount amps in a battery?
2) If one has a pinhole camera and consumes 400mW, how many hours can this camera consumes from a 9V battery?
3) Is there a better way how to understand the connection between volts, wattage and amps?
I am new to electronics. Thanks.
