A mica capacitor and a ceramic capacitor both have the same physical dimensions. Which will have more value of capacitance ?

The correct answer is: A. Ceramic capacitor.

A ceramic capacitor has a higher capacitance than a mica capacitor of the same physical dimensions. This is because ceramic capacitors are made of a material with a higher dielectric constant than mica. The dielectric constant is a measure of how well a material can store an electric charge.

Ceramic capacitors are also more stable than mica capacitors, meaning that their capacitance does not change as much with temperature or applied voltage. This makes them a better choice for many applications, such as filters and oscillators.

Here is a brief explanation of each option:

• Option A: Ceramic capacitors have a higher capacitance than mica capacitors of the same physical dimensions. This is because ceramic capacitors are made of a material with a higher dielectric constant than mica. The dielectric constant is a measure of how well a material can store an electric charge.
• Option B: Mica capacitors have a higher capacitance than ceramic capacitors of the same physical dimensions. This is not true. Ceramic capacitors have a higher capacitance than mica capacitors of the same physical dimensions.
• Option C: Both will have identical value of capacitance. This is not true. Ceramic capacitors have a higher capacitance than mica capacitors of the same physical dimensions.
• Option D: It depends on applied voltage. This is not true. The capacitance of a capacitor does not depend on the applied voltage.
