Question 1 Report

Two capacitors R1 = 4 $Ω$ and R2 = 5 $Ω$ 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

4 : 5

5 : 4

16 : 25

25 : 16

Answer Details

P1 = $\frac{V_{1}^{2}}{R_{1}}$ and P2 = $\frac{V_{2}^{2}}{R_{2}}$

P1R1 = P2R2

4P1 = 5P2

$\frac{p_{1}}{p_{2}}$ = $\frac{5}{4}$

= 5 : 4
