If a camera draws 1 amp.,and I connect it to a battery that can supply
10A,will it do any harm to the camera ,IF the volts correct for the
camera?
Thanks.
No. The batteries set the upper bound on how much current a load can
draw (the short circuit current) and a practical upper bound on load
current, based on the capacity (ampere hours) and internal resistance
(that lowers the voltage as the load current drops some of the voltage
across the internal resistance. But if neither of these limits is in
effect, the load just uses as much current as it needs. A bigger
battery just lasts longer.
