Electricity (physics NOTES)
Notes of ch-12 Electricity (by Manish Sharma) Electricity: Electricity is the sey of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electric current: Electric current is the rate of flow of electrons in a conductor.The S.I unit of electric current is the Ampere. Electric potential: Electric potential , the amount of work needed to move a unit charge from a reference point to a specific point against an electric field . Potential difference: The electric potential energy of any given charge or system of changes is termed as the total work done by an external agent in bringing the charge or the system of charges from infinity to the present configuration without undergoing any acceleration. Definition: Electric potential energy is defined as the total potential energy a unit charge will possess if located at any point in the outer space. general formula is Voltage = En...
