MCQ
Statement$-I :$ To get a steady de output from the pulsating voltage received from a full wave rectifier we can connect a capacitor across the output parallel to the load ${R}_{{L}}$

Statement$-II :$ To get a steady de output from the pulsating voltage received from a full wave rectifier we can connect an inductor in series with ${R}_{{L}}$.

In the light of the above statements, choose the most appropriate answer from the options given below:

  • A
    Statement $I$ is true but Statement $II$ is false
