## FAQs on Introduction to Electric Charges Video Lecture - Physics Class 12 - NEET

 1. What is an electric charge?
Ans. Electric charge is a fundamental property of matter that can be positive, negative, or neutral. It is a property of subatomic particles, such as electrons and protons, that determines how they interact with each other.
 2. What is the difference between positive and negative charges?
Ans. Positive charges are associated with protons, which have a positive charge, while negative charges are associated with electrons, which have a negative charge. Positive and negative charges attract each other, while like charges repel each other.
 3. How is electric charge measured?
Ans. Electric charge is measured in units called coulombs (C). One coulomb of charge is equal to the amount of charge that flows through a wire in one second when a current of one ampere (A) is flowing.
 4. What is the relationship between electric charge and electric current?
Ans. Electric current is the flow of electric charge through a conductor. The rate at which electric charge flows is measured in units of amperes (A), which is defined as one coulomb of charge per second.
 5. How can electric charge be transferred from one object to another?
Ans. Electric charge can be transferred from one object to another through a process called charging. This can happen through contact, where electrons are transferred from one object to another, or through induction, where a charged object can influence the distribution of charges in an adjacent object without touching it.
