Figure shows three resistor configurations R1,R2 and R3 connected to 3 V battery .

If the powers dissipated by the configuration R1,R2 and R3 are P1,P2 and P3, respectively, then

A

(a)`P_1 lt P_2 lt P_3`

B

(b)`P_1 gt P_3 gt P_2`

C

(c)`P_2 gt P_1 gt P_3`

D

(d)`P_3 gt P_2 gt P_1`

Text Solution

Verified by Experts

Applying `P=V^2/R, R_1=1 Omega R_2=0.5 Omega and R_3=2 Omega`
`therefore P_1=(3)^2/1=9w, P_2=(3)^2/0.5=18w and P_3=(3)^2/2=4.5W`
