Ambeer

Ambeer ama Ampere (calaamad: A), oo inta badan lagu soo gaabiyo amp, waa unugga hadda korantada ee Nidaamka Caalamiga ah ee Unugyada (SI). Hal ampere waxa ay la mid tahay 6.241509074×10¹⁸ elegteroon qiimihiisu waxa uu dhaafayaa dhibic ilbiriqsi gudaheed.

Waxaa loo magacaabay ka dib markii xisaabyahan Faransiis ah iyo fisiigis André-Marie Ampère (1775-1836), loo arkaa aabbihiis elegteromagneetism oo uu weheliyo physicist Danish Hans Christian Ørsted.

Xisaab

1 Maayad (ampere) = 1 kulaam\1amin (ilbirisi)

$\mathrm{1}\mathrm{A}\mathrm{=}\mathrm{1}\frac{C}{s}$

Qaanuunka (ohm) sida uu qabo 1 maayad = 1 volt\ ohm

Tamar-kayd = Maayad X Caabi

• · Tamar-kaydka halbeegeedu waa Volt.
• · Maayada halbeegeedu waa Ampere.
• · Caabiga halbeegiisu waa Ohm.

Milli ampere =1000/1 ee maayad.

Mikro ampere =1000,000/1 ee maayada.

$1\mathrm{A}=\frac{1\mathrm{C}}{1\mathrm{s}}=\frac{1\mathrm{V}}{1\mathrm{\Omega }}=\frac{1\mathrm{W}}{1\mathrm{V}}$
