A battery with an emf of 9.6 V andinternalresistance of 1.08 Ω carries a positive current of 0.455Afrom its negative terminal to its positive terminal.
(a) How long is required for 0.90 C of charge to pass throughthebattery?
1.98 s
(b) By how much will the electrical potential energy of 0.90 Cofcharge increase in crossing the battery terminals?
8.2 J
(c) By how much will the chemical energy decrease?
____ J
(d) How much electrical power is supplied by the battery?
4.14 W
(e) At what rate is chemical energy used?
___ W
I don't understand C and E. Can someone help, please?
