Electric current(I)

  • The flow of electric charge is greatly known as electric current.
  • A flow of charge carriers is usually electron and electron-deficient atoms.
  • It is represented by:  I= Q/t

Drift velocity of the electron

Battery and it's working

Electric circuit

Electric circuit and circuit diagram

  • A closed-loop path which is taken by the current is known as an electric circuit.
  • Representation of an electric circuit with the help of different types of symbols is known as a circuit diagram
