Answer:
option c
Explanation:
The temperature must be constant. Ohms law states that the current running through a conductor is directly proportional to the potential difference across it provided the temperature remains constant
Answer:
Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2

when we switch on the lamp, vibrations of electric and magnetic fields will release energy to its surrounding environment. Which the reason why the area around the lamp will feel warmer when we light it up.</span>
