Class 12 Physics Current Electricity Introduction

Introduction

  • We are going to learn about how the charges which are in motion constitute the current, to study how current is used in our daily life.
  • For example: -
    • Glowing of bulb by switching on and off the switch.
    • All the electrical appliances work when the current passes through them.
    • Washing machines, iron box,battery,TV,laptop and so on.
  • In this chapter we will be able to give answers for the following questions :-
    • How electric current is produced by the movement of charges?
    • What are the different properties of current?
    • What constitutes the electric current?
    • What are the different laws which govern the electric currents?
