Question

A capacitor of 10 \(\mu\) F charged up to 250 V is connected in parallel with another capacitor of 5 \(\mu\) F charged up to 100 V. The common potential is:
a)200V
b)300V
c)400V
d)500V

Answer 1

200volt

Answer 2

common potential= (10X250+ 5X100)/(10+5)

Answer 3

How?

Answer 4

expressio for common potential when two charged capacitor are connected is
(CaXVa+CbVb)/(Ca+Cb)

Answer 5

if in series?

Answer 6

till i know only parallel
if u will get about series dont forgrt me ok bro

Answer 7

ok bro!

Answer 8

i think exp will be same since expression is derived from theory of conservation of charge

Answer 9

Thanks bro!
