Question

Two capacitors c1 =2microfarad and c2=4microfarad are connected in series and a potential difference of 1200v is applied across it,the potential difference across 2microfarad will be

Answer 1

answer is 800 microfarad

Answer 2

Q = V×Ceq.
Ceq.= (2 ×4)/(2+4) = 4/3
Q= 1200×4/3 = 1600
V1 = 1600/ 2 =800 v .
