Statement I: Displacement current arises on account of change in electric flux.
Statement II: Conduction current arises due to the flow of electrons through the connecting wires of a circuit in a closed path
Statement II: Conduction current arises due to the flow of electrons through the connecting wires of a circuit in a closed path
View answer and explanation
Correct option: A
Statement I and statement II are true
Option A (Statement I and statement II are true) is correct because both statements accurately describe displacement and conduction currents.

Statement I: Sound waves are not electromagnetic waves.
Statement II: Sound waves require a material medium for propagation. For a plane electromagnetic wave propagating in x-direction, which one of the following combination gives the correct possible directions for electric field and magnetic field respectively? Assertion: The relative velocity of two photons travelling in opposite directions is the velocity of light.
Reason: The rest mass of photon is zero Intensity of electromagnetic wave will be The rms value of the electric field of the light coming from the Sun is . The average total energy density of the electromagnetic wave is Methane is a greenhouse gas because
