What is the linear resistor.

G K 7 years, 1 month ago

Linear resistance is the property of a resistor whose resistance doesn't change with change in factors like temperature, voltage across its leads etc. These resistors obediently obey Ohms Law [ V=IR ], i.e current through the resistor is directly proportional to the voltage applied across it.

Sambhav Chopra 7 years, 1 month ago

ELECTROMAGNETIC INDUCTION :-- The phenomenon of production of Electric current in a closed loop by varying magnetic field across it . NOTE :-- 1.) When a changing magnetic field passes through a loop (open), an e.m.f. is induced in the loop. 2.) If the loop is closed , then a current flows through it , which is called as Induced Current.

ANSWER

Why use gauss law?

Posted by Madhav Rajput 7 years, 1 month ago

CBSE > Class 12 > Physics

2 answers

G K 7 years, 1 month ago

First of all we use Gauss's law because it is a law of nature! Second: Gauss's law (together with ∇×E⃗ =0, which is only strictly valid in electrostatics) is equivalent to Coulomb's law for the electric field of a distribution of charges. You can prove one from the other. Third: You a right about external fields cancelling. Gauss's law essentially says that electric field lines only end on charges. So if you have a volume that doesn't contain a charge, any field line which enters will also leave and the total flux through the closed surface is zero. Fourth: In the sphere problem is the sphere a conductor? If so it screens anything happening outside the sphere. If the sphere is not a conductor then the field inside will depend on what is happening outside, but the total flux through the sphere will only depend on what's inside.
