Also,

Im not sure if I am using this formula correctly but here is what I calculated:

C(equivalent)=Q1/V + Q2/V

C(equivalent)=12000/25V + 4.7/100V

C(equivalent)=48000/100V + 4.7/100

C(equivalent)=48004.7/100V

However, is 100V even possible since one of the capacitors is only 25V .

Thanks in advance for any help...
