Question

A capacitor of capacitance C is charged upto 90 V and then connected to an uncharged capacitor of capacitance 2C. The final potential difference across
each capacitor will be
O 45 V
O 30 V
O 90 V
O 60 V​

Answer 1

Explanation:

right reply me please vai..or..dada

Answer 2

Answer:

30V

Explanation:

(C1+C2)V = (C+2C)V

C x 90 + C x 0 = 3C(V)

90C = 3CV

30 = V
