Charges & Electric Current
Static Electricity: Charges @ Rest
COncept of charge
: An object is said to be charged when there is imbalance of numbe rof electrons & Number of protons.
Ne = Np } Neutral
Np< Ne : Negative Charge
Np>Ne } Positive Charge
Charged atom is called ION
Conservation of charge
Methods of Charging: The Protons cannot move as they are inside nucleus and so only electrons are lost & gained for process of charging.
Conduction
An already charged object gives or takes electrons from another object by coming in contact.
Induction
When one charged object is brought close (without touching) to the neutral object, it induces a charge in neutral object temporarily. If we want to charge something permanently using induction we have to follow
4 specific steps.
Triboelectric Effect
Charging by rubbing two objects. Both obejcts start off as neutral.. Once rubbed one object gains electrons and other object looses electrons.
Electrostatic Phenomenon
Lightning
ESD
