Amp is a measure of coulombs (charge) per second. No need for an additional unit of time.I get 40mA draw is the circuit or whatever it is, is drawing 40mA due to internal resistance and such. But when people say 40mA current draw, does it mean 40mA per second, minute, hour,
No. Ampere is already charge per second.I get 40mA draw is the circuit or whatever it is, is drawing 40mA due to internal resistance and such. But when people say 40mA current draw, does it mean 40mA per second, minute, hour,
Way to @KeepItSimpleStupidWhile we are here, we might as well bring up "conventional current". It "flows" positive to negative, I just have to warn you that when you deal with other subjects like electrochemistry stuff will seem backwards and they are. Your instrumentation,like a voltmeter will read a positive value when + is connected to + of the meter and - is connected to - of the meter. This is probably all you need to know now.
