LEEM-16 Dielectric Constant Apparatus

Iinkcukacha zeMveliso

Okuqulathwe kuvavanyo oluphambili

1. ukulinganiswa kwe-vacuum permittivity e0 kunye ne-relative permittivity er;

2. indlela yokufunda i-LC resonance yokulinganisa amandla amancinci;

3. ukufunda ukusebenzisa i-oscilloscope yedijithali.

Iiparameter eziphambili zobugcisa

Deumbhalo	Iinkcukacha
