What do u mean by electric current? electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles).
What do you mean by electric current? : a movement of positive or negative electric particles (such as electrons) accompanied by such observable effects as the production of heat, of a magnetic field, or of chemical transformations — compare alternating current, direct current, displacement current.
What do u mean by electric current class 10? Electric current is rate of flow of electric charge or the amount of charge flowing through a particular area in unit time. … In reality, electric current is flow of negatively charges particles called electrons.
Do protons accelerate in an electric field? The arrow heads show the direction in which a positively charged particle (such as a proton) would accelerate if it was placed in the electric field. A negatively charged particle (such as an electron) would accelerate in the opposite direction to the arrow heads.
