Electric Circuit by lisamicallef. Components of circuit by Edmarie. This set up is called electric cell and connection of electric c ells produce battery. There must be a potential difference between the electrodes to make charges flow. Electric Current and Flow of Charge.
If we connect the conductor to a battery, potential difference between the ends of the conductor occurs. This potential difference creates an electric field towards to the positive end of the conductor to the negative end.
E in this field. Under the effects of this force electrical charges starts to flow. This flow of charge is called electric current. We can make an analogy with heat transfer. As we discussed in earlier chapters, heat flows from matter having higher temperature to the lower temperature. In this case charges flows from higher potential to the lower potential.
Electric current, in solids transferred with the free electrons, in liquids with free ions and in gases with free electrons and free ions.
We can also define electric current as the charge per unit time passing through the cross section of conductor like given in the picture which is shown with red dashed lines.
Average current is found with the following formula;.
