Otu esi ebelata mfu nke induction agbaze ọkụ induction coil na mmiri jụrụ oyi USB?

Ịbawanye dayameta nke eriri induction na eriri mmiri na-ekpo ọkụ ga-ebelata njupụta ya ugbu a, belata nkwụsị ọkụ nke eriri ọkụ ọkụ, ma na-enye aka belata okpomọkụ gburugburu ebe obibi nke induction coil na mmiri USB, ma belata nhazi nke ọnụ ọgụgụ. Iji

A na-enweta ike eletrik nke eriri induction na t℃ site na usoro a:

W=I2R×10-3=I2P20L/A×[1+α（t-20)]

W n’usoro a dị n’elu – ike nke eriri induction, KW;

Ana m ebu ihe dị ugbu a, A;

R―The resistivity nke induction eriri igwe na 20℃, Ω · m 2.2×10-8;

L – ogologo nke eriri induction, m;

A-ofe akụkụ nke eriri induction, m2;

P20- The resistivity nke ọla kọpa na 20 ℃, Ω · mm2 · m-1;

α― The okpomọkụ ọnụọgụ nke iguzogide electrolytic ọla kọpa, 4.3 × 10-3 / ℃.
