Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa sababta fiilooyinka dhaadheer ay u leeyihiin iska caabin ka sarraysa fiilooyinka gaagaaban.

Hordhac

Salaan, waxaan ahay Dr. de Mello, oo maanta idin baraya darsiga dhererka siliga. Darsigani wuxuu ka mid yahay cutubka iska caabbinta (resistance) iyo wareegyada barbar socda, waxaana horey uga yaqaan sida korontadu u socoto wareegga. Darsigan waxaad ku baran doontaa sababta siliga dheer uu u leeyahay iska caabin sare marka loo barbar dhigo siliga gaaban, iyadoo la adeegsanayo fikradaha aad horey u taqaanay.

Muuji qoraalka
The longer a wire, the greater its resistance. Electric current in a wire is a flow of electrons moving through the spaces between ‘atoms’ (metal ions). Doubling the length of a wire doubles its resistance. Doubling the length of a wire doubles the number of ‘atoms’ (metal ions) in the way of the flow of electrons. The resistance of a (uniform) wire is proportional to its length.
