Qiyaasta danabka

Maanta waxaan baranaynaa sida loo qiyaaso korantada (voltage) iyo sida ay u saameyso wareegyada korantada. Horeyba waxaad u taqaanay sida korontadu u socoto wareegga, iyo in batterigu bixiyo tamar. Ereyada muhiimka ah waxaa ka mid ah: voltmeter (qalabka qiyaasa korantada), voltage (korantada), potential difference (farqiga awoodda, oo loo soo gaabiyo p.d.), volts (halbeegga korantada, oo leh xarafka V), iyo battery (batteri).
