Key Concepts
Electric current is the rate
Electric current is the rate of flow of electric charges (electrons) through a conductor. It is represented by the symbol 'I' and is defined mathemati
An electric circuit is a closed
An electric circuit is a closed conducting loop or path made using electrical wires that connects an electric appliance to a source of electric charge
Electric potential at a point
Electric potential at a point is the work done in moving a unit positive charge from infinity to that point against electric force. Electric potential
Ohm's Law establishes the relationship between
Ohm's Law establishes the relationship between potential difference (V), current (I), and resistance (R) at constant temperature. The law states that
Resistance is a material's property
Resistance is a material's property to oppose the flow of electric charges through it. It is the ratio of potential difference to current: R = V/I. Th
