How to cover syllabus when I am too back?

Rishabh Sahu 7 years, 4 months ago

Understanding the material is important while studying syllabus. Read all topics and attempt questions based on them . Then first mark those topics which you didn't understand in the first reading. Then mark those topics which you thought you understood but on attempting questions you found that actually you didn't. Then look for an easier explanation to these topics from other sources and or take help from teachers and friends. If you are just behind only in terms of memorizing the topics /points then read ,write and do continuous revision. After each revision even if you don't remember everything a chunk will be left in a piece of your mind and finally you will remember most of the things.

Sia ? 4 years, 3 months ago

``Induced emf'' is the more general term. If the changing emf is due to some kind motion of a conductor in a magnetic field, you would call it a ``motional emf''. For example, if a loop moves into or out of a region of field, or rotates, or a bar rolls along a rail, you'd get a ``motional'' induced emf.

Explain electrostatic shielding?

Posted by Himanshu Ramaria 7 years, 4 months ago

CBSE > Class 12 > Physics

1 answers

Priyanshu Sharma 7 years, 4 months ago

The electric field inside a hollow conductor is zero. If an object is located inside the hollow conductor then there will be no effect of electric field on the object. Hence we can say that hollow conductor provide shield to the object from external electric field. This is known as electrostatic shielding...
