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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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
