List-I
a. improve power factor
b. reduce the current ripples
c. increase the power flow in line
d. reduce the Ferranti effect

List-II
1. shunt reactor
2. shunt capacitor
3. series capacitor
4. series reactor

(A) a " 2, b " 3, c " 4, d " 1
(B) a " 2, b " 4, c " 3, d " 1
(C) a " 4, b " 3, c " 1, d " 2
(D) a " 4, b " 1, c " 3, d " 2


Answer: B

*.shunt capacitors are used to improve power factor
*.series reactors are used to reduce current ripples
*.series capacitors are used to increase power flow in line
*.shunt reactors re used to reduce the ferranti effect.
