    I believe that atleast one month before the board exams, we are expected to cover all the main concepts and theory part. And now the question arises that what to do in the last remaining month? I would suggest you to give your last one month only and only on solving the previous year board papers and sample papers. It will help you in better understanding all the main concepts and will give you the idea about the most important part of the topic which is being asked again and again in last ten or fifteen years,etc. Moreover it will boost your speed and accuracy which is the most important tool for a topper. Thank you! Hope it helps you... Best wishes

    But displacement current should be present at the time of charging of the capacitor because at that time flux changes how come the displacement current is zero then

    1Thank You

    Aman Deep 7 years, 10 months ago

    During during initial time the capacitor get charged that time displacement current is zero and conduction current is there and and when the capacitor get charged fully then there is no conduction current but on the displacement current is present

    Refraction. When light travels from one medium to another, the speed changes, as does the wavelength. The index of refraction can also be stated in terms of wavelength: Although the speed changes and wavelength changes, the frequency of the light will be constant

    The shifting of zero of the scale at different points as well as the stray resistance give rise to the end error in meter bridge wire. This error arise due to the non uniformity of the meter wire End corrections can be estimated by including known resistances P1 and Q1 in the two ends and finding the null point
