electric current

in our daily lives can never be separated from the name electric currents. very closely with the current electricity and voltase.ok ... this time we will try to find out more on what the current and voltage

  • electric current


electric current is the amount of electric current in units time.for example if we open the water tap in one second and hold water in a glass then it could be the URLs of the number of existing water current.altought in glass as we open the faucet same one second is not necessarily water who go out at this much.this is depending on the size we open valve.ok ... this difference if the applied electric current is called by difference where current flows are denoted by letter "I" and its unit ampere "A"

  • voltage


also called a potential difference of electrical power that giveselectric . current flow of water will not flow if there is no height difference, it also applies to the theory of  difference listrik.because equivalent high voltage electrical .current will easily flow when a high voltage and vice versa current will flow in voltage low.voltase difficult symbolized by the "V" with units of volts
