The word current derived from Latin word “currere” (meaning run, flow, move) has resulted in the word ... Often current is indicated by amp or Amp, but both of them are informal and unofficial. ... The reciprocal of resistivity is called the conductivity and is represented by the Greek letter sigma,σ. Mathematically, σ = 1/ρ and the unit ...
