Solution
The correct option is C
The total charge the battery can deliver is Q = 100 A× 1 hour = 100×3600 As = 360000 C. A fully charged capacitor will have a charge of 
. The number of capacitors = Q/q
The total charge the battery can deliver is Q = 100 A× 1 hour = 100×3600 As = 360000 C. A fully charged capacitor will have a charge of
. The number of capacitors = Q/q
