Nkọwa nke ike eletrik
A na-ekpebi ike a mụtara n'ọrụ na ike dị ka ọrụ e mere n'oge ụfọdụ. Ọrụ bụ usoro mgbanwe ike ka e wee ghọta ike dị ka mgbanwe ike nke na-eme n'oge ụfọdụ.
Ike eletriki bụ mgbanwe na ike eletriki n'oge ụfọdụ. Na nyocha nke ike eletriki, a kọwara na mgbanwe na ike eletriki na-eme mgbe chaja eletrik gafere ọdịiche ike eletriki.
Nha nke ike eletrik
N'ihe gbasara mgbakọ na mwepụ, mgbanwe dị na ike eletrik (ΔEP) dabere na chajị (Q) na voltaji eletrik (V), nke e gosipụtara site na nha ΔEP = Q V.
Ike bụ mgbanwe na ike eletrik n'ime oge ụfọdụ, nke e gosipụtara na mgbakọ na mwepụ site na usoro 1:
Chajị eletriki nke na-aga n'oge oge ụfọdụ bụ ọkụ eletrik, nke a na-egosipụta site na mgbakọ na mwepụ site na nha anya I = Q/t. Enwere ike ịgbanwe nha anya 1 ka ọ bụrụ nha anya 2:
Dabere na nha nha abụọ a, enwere ike ikwubi na mgbanwe na ike eletriki n'oge oge ụfọdụ na-eme mgbe ọkụ eletrik gafere ọdịiche ikike eletriki ụfọdụ. Ike eletriki kwekọrọ na ike nke ọkụ eletrik na ike eletrik, yabụ ọ bụrụ na ọkụ eletrik na ike eletrik amụba, ike eletrik na-abawanyekwa.
Ọ bụrụ na ọkụ eletrik na-agafe na resistor nke nwere ike iguzogide eletriki mgbe niile, enwere ike ịgbakọ ike eletrik site na iji usoro 3 ma ọ bụ usoro 4.
Nkeji nke ike eletrik
Dabere na nhazi nke 1, nkeji Sistemụ Mba Nile nke Ike bụ Joule na nkeji Sistemụ Mba Nile nke oge bụ nke abụọ nke mere na nkeji ike eletrik bụ Joule/sekọnd, nke a na-akpọ J/s. A na-akpọkwa Joule/sekọnd Watt. 1 Watt = 1 Joule/sekọnd.
Dabere na usoro nke 2, nkeji nke ike eletrik bụ Volt na nkeji nke ọkụ eletrik bụ Ampere ka nkeji nke ike eletrik bụrụ Volt Ampere, nke a na-akpọ VA.
