A solar cell provides an emf of 0.15 V.
(a) If the cell supplies a constant current of 25.0 mA for 6.0 h, how much electrical energy does it supply?
J
(b) What is the power - the rate at which it supplies power?
J/s
Answers:
A)
q=I*delta_t
q=25.0x103 * 6(60*60)=
540C
540C*.15V =
81J
B)
81J/6(60*60)=
.00375J/s
