Jelaskan Fisik dari Kapasitor dalam bahasa sunda

Kapasitor diwangun ku dua éléktroda, atawa pelat konduktif, nu dipisahkeun ku isolator

Kapasitansi kapasitor (C) nyaéta ukuran muatan (Q) nu kasimpen dina unggal pelat pikeun hiji béda poténsial atawa tegangan (V) nu mucunghul antara pelat-pelat éta:

Dina hijian SI, kapasitor mibanda kapasitansi safarad lamun sacoulomb muatan nyababkeun béda poténsial savolt pikeun sakabéh pelat. ku sabab farad téh nyaéta hijian nu kacida gedéna, ajén kapasitor biasana diungkabkeun dina microfarad (µF), nanofarad (nF) atawa picofarad (pF).

The capacitance is proportional to the surface aréa of the conducting plate and inversely proportional to the distance between the plates. It is also proportional to the permittivity of the dielectric (that is, non-conducting) substance that separates the plates.

The capacitance of a parallel-plate capacitor is given by:

where ε is the permittivity of the dielectric, A is the aréa of the plates and d is the spacing between them.

In the diagram, the rotated molecules créate an opposing electric field that partially cancels the field créated by the plates, a process called dielectric polarization.
