Question
Figure shows three resistor configurations R1, R2 and R3 connected to 3V battery. If the power dissipated by the configuration R1, R2 and R3 is P1, P2 and P3, respectively, then
Figure:
Figure:
Options
A.P1 > P2 >P3
B.P1 > P3 >P2
C.P2 > P1 >P3
D.P3 > P2 >P1
Solution
P = 
R1 = 1Ω, R2 = 1/2Ω, R3 = 2Ω
∴ P2 > P1 > P3
R1 = 1Ω, R2 = 1/2Ω, R3 = 2Ω
∴ P2 > P1 > P3
