Question -
Three resistances of equal value are connected in four different combinations as shown in figure. Arrange them in increasing order of power dissipation
Options:
A .  III
B .  II
C .  I
D .  I
Answer: Option B : B Let R be the value of each resistance. The resistances of combinations I, II, III and IV are 3R, 2R3, R3 and 3R2 respectively. Now power dissipation is inversely proportional to resistance
