Natiijada casharka

Waxaan isbarbardhigi karaa iska caabbinta korantada ee qaybaha kala duwan iyadoo la adeegsanayo cabbirada xoogga korontada (current).

Hordhac

Casharkani wuxuu ku saabsan yahay iska caabbinta korontada (electrical resistance), waxaana ka mid ah cutubka 'Iska caabbinta iyo Wareegyada Barbaraha'. Waa inaad hore u garanaysaa sida korontadu (current) ugu socoto wareeg fudud iyo sida loo cabbiro iyadoo la isticmaalayo ammeter.

Muuji qoraalka

An ammeter measures current in amps (A). Resistance is a measure of how difficult it is for a current to flow. Resistance is measured in ohms (Ω). In a fair test, only the independent variable is changed so that no other variables affect the results. The variables that are deliberately kept the same are called control variables.
