1. ELECTRIC CURRENT:-<\/span><\/u><\/strong><\/p>\n

Electric current is defined as the flow of charge through a given area of the substance.<\/span>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/p>\n

Direction of electric current:-<\/span><\/strong><\/p>\n

The direction of flow of positive charge or the direction in which electric field is applied gives the direction of electric current. This current is called\u00a0<\/span>conventional current<\/span><\/em><\/strong>.\u00a0<\/span><\/strong><\/p>\n

Unit of electric current:-<\/span><\/strong><\/p>\n

S.I unit of electric current is Ampere (A)<\/span><\/strong><\/p>\n

Current through a conductor is said to be 1 ampere if one coulomb charge flows through any cross sectional area of the conductor in one second.\u00a0<\/span><\/p>\n
