Question

s. The capacitance of a capacitore will decrease with if we introduce which slab of the following (a) copper b) aluminium (e) zine d none of these​

Answer 1

The answer is "a".

Copper

Because all are conductors with very high dielectric constant. Presence of material increases capacitance in proportion to the dielectric constant.

Answer 2

The capacitance of a capacitor will decrease with if we introduce which slab of copper.

• Aluminium and zinc are metals with very high dielectric constant.
• If a slab of a metal with high dielectric is introduced, the capacitance will increase.
• According to the formula, C = Kε₀A / d.

• Here, C is the capacitance, K is the dielectric constant, ε₀ is the permittivity of free space, A is the area of the slab and d is the distance between the plates.
• As evident from the formula, dielectric is directly proportional to the capacitance.
• Since copper doesn't have a high dielectric, the introduction of it will decrease the capacitance.
