how many coulombs are provided by a current of 0.01 ma in the calculator battery that can operate for 1000 hours
DearStudent,
Formula used is Q=It
where Q= Charge in coulomb
I= Current in ampere
t= time in seconds
Given, I= 0.01 mA = 0.01 * 10-3 A, t= 1000 hrs = 1000 * 60 * 60 sec
Q = I*t = (0.01 * 10-3 A)*(1000 * 60 * 60 sec) = 36 C
Hence Charge is 36 C.
Regards
