Question # 1

Define Time constant for RC Circuit.

  • Ans 1: The time required by the capacitor to deposit 0.63 times the equilibrium charge q is called time constant.The product of R and C has the dimensions of time.So this product is known as time constant.

Question # 1

What is electric potential energy and electric potential difference?

  • Ans 1: Electric potential energy: The energy is acquired by unit positive charge in carrying it from one point to the other against the electric field keeping it in electrostatic equilibrium is called as electric potential energy,It is the energy stored in the charge 'q' because of its position in an electric field.It is measured in joules.
  • Ans 2: Electrical potential difference: The electric potential difference between two points is defined as the work done in carrying a unit a positive charge from one point to other point while keeping the charge in electrostatic equilibrium.
