| Directions (Q. No. 1 to 5): |
| Read the following text and answer the following questions on the basis of the same: |
| Super capacitor: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits. Such capacitors bridges the gap between electrolytic capacitors and rechargeable batteries. |
| In automobile, bus, train, crane, elevator such capacitors are used for regenerative braking, short term energy storage or burst-mode power delivery. |
| Super capacitors have many advantages over batteries: they are very low weight and generally don't contain harmful chemicals or toxic metal. |
| They can be charged and discharged innumerable number of times without ever wearing out. |
| The disadvantage is that super capacitors aren't well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20% of their charge per day due to self- discharge. |
A) very low.
B) medium.
C) very high.
D) may have any value.
Correct Answer: C
Solution :
Option [c] is correct. Explanation: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits.
