Maayad ama Ampeere Sumadeeduna waa (A) waxaa lagu cabiraa koronto ama waxii dab ah oo dhan ee ka sameysan Elektariik. 1 Maayad (ampere) = 1 kulaam\1amin (ilbirisi) 1   A = 1 C s {\displaystyle {\rm {1\ A=1{\tfrac {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 A   = 1 C 1 s = 1 V 1 Ω = 1 W 1 V {\displaystyle 1\,\mathrm {A} \ ={\frac {1\,\mathrm {C} }{1\,\mathrm {s} }}={\frac {1\,\mathrm {V} }{1\,\Omega }}={\frac {1\,\mathrm {W} }{1\,\mathrm {V} }}}
