JEE Main 31 August 2021, Shift 2, Physics Q18

Question 18 of 90 in this shift, Physics question 18 of 30, Section A.

Statement I : To get a steady dc output from the pulsating voltage received from a full wave rectifier we can connect a capacitor across the output parallel to the load RLR_L. Statement II : To get a steady dc output from the pulsating voltage received from a full wave rectifier we can connect an inductor in series with RLR_L. In the light of the above statements, choose the most appropriate answer from the options given below :
  1. (1)Both Statement I and Statement II are trueOfficial answer
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is true but Statement II is false
  4. (4)Statement I is false but Statement II is true
