and please make my answer as the BRAINLIEST one.

Answer 2

(a) The capacitor which has a dielectric between its plates and is made of a flexible material that can be rolled into the shape of a cylinder is called ceramic capacitors.

Explanation for correct answer:

Option (a) is the correct answer.

• Capacitors are used for storing energy.
• The capacitor are generally made of two metal plates separated by a small gap.
• If the gap is filled with dielectric material, then they can store more amount of energy.
• Ceramics are materials which can be flexible in nature and it can be molded into cylindrical shape easily.
• So, the dielectric used in the capacitors are mostly ceramic materials as they are good insulators also.
• Thus, ceramic capacitors is the right answer.

Explanation for wrong answer:

Option (b) is wrong answer.

• Fixed capacitors does not contain flexible materials.
• Mostly, they capacitors with no dielectric materials in the gap.

Option (c) is wrong answer.

• Parallel plate capacitors can contain dielectric materials.
• But as the plates are parallel to each other, mostly the dielectric material has to be in rectangular shape to be fitted in the gap.
• So, the dielectric material cannot be cylindrical in shape in parallel plate capacitor.

Option (d) is wrong answer.

• Electrolytic capacitor consists of electrolytes as dielectric medium.
• So, solution act as dielectric and not any solids in this case.
• So, this is also not the correct answer.

Final Answer:

Ceramic capacitors consists of flexible and cylindrical dielectric materials in it.
