Maxwell third equation and its derivation
Statement.(a) It states that,whenever magnetic flux linked with a circuit changes then induced electromotive force (emf) is set up in the circuit. This induced emf lasts so long as the change in magnetic flux continues. (b) The magnitude of induced … Continue reading
Maxwells first and second equations and their derivation
Maxwell’s first equation or Gauss’s law in electrostatics Statement. It states that the total electric flux φE passing through a closed hypothetical surface is equal to 1/ε0 times the net charge enclosed by the surface: ΦE=∫E.dS=q/ε0 ∫D.dS=q where D=ε0E= Displacement … Continue reading

DISTORTIONLESS LINE
Definition DISTORTIONLESS LINE A transmission line is said to be distortionless when attenuation constant ‘α’ is frequency independent and the phase shift constant ‘β’ is linearly dependent on the frequency. Condition for line to be distortionless
