ବିଦ୍ୟୁତ୍ ସ୍ରୋତ ମାପିବା ପାଇଁ ବ୍ୟବହୃତ [[International System of Units|SI]] ୟୁନିଟ ହେଉଛି [[ampere|ଆମ୍ପିଅର୍]], which is the flow of electric charge across a surface at the rate of one [[coulomb]] per second. Electric current is measured using a device called an [[ammeter]].<ref name="learn-physics-today" >{{cite web
