1. The problem statement, all variables and given/known data Two capacitors having values of 10 μF each are connected in parallel and then hooked up to a 9.0 V battery. How much energy must the battery supply to charge the capacitors? *a. 8.1 x 10-4 J b. 9.0 x 10-5 J c. 1.6 x 10-3 J d. 2.0 x 10-4 J e. 2.3 x 10-5 J 2. Relevant equations ε=ΔW/ΔQ Q=CV ΔW=ΔE C=C1+C2...+Cn (for capacitors in parallel) 3. The attempt at a solution ΔE=ε*ΔQ ΔE=ε*CV ΔE=9V*(10μF+10μF)*9V ΔE=1.62x10-3 J the answer key says A is correct...can someone tell my why?
