Two capacitors R1 = 4(Omega) and R2 = 5(Omega) are connected in parallel across a potential difference. If P1 and P2 represent power dissipated in R 1 and R2 respectively, then the ratio P1 : P2 is
-
A.
4 : 5 -
B.
5 : 4 -
C.
16 : 25 -
D.
25 : 16
Correct Answer: Option B
Explanation
P1 = (frac{V^2_1}{R_1}) and P2 = (frac{V^2_2}{R_2})
P1R1 = P2R2
4P1 = 5P2
(frac{p_1}{p_2}) = (frac{5}{4})
= 5 : 4
