Hi.
Could anyone advise please

1 led drawing 10mA off a 12volt car battery,how long would
take to use up 1amp of the battery.

Thanks.
.Baz

Am I right in saying it would take 100hrs,could someone confirm please.


I assume you mean "use 1 ampere-hour".

10 mA is 0.01 Amp (1/100 Amp), so it would take 100 hours for the 10
mA LED to consume 1 AH.
