Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)
The continuity equation is a combination of which of the two laws?
A)
Ohm’s law and Gauss law
B)
Ohm’s law and Ampere law
C)
Ampere law and Gauss law
D)
Maxwell law and Ampere law

Correct Answer : Option (C) :   Ampere law and Gauss law


Explanation : I = ∫ J.ds is the integral form of Ohm’s law and Div (J) = dq/dt is the Gauss law analogous to D. Through these two equations, we get Div(J) = -dρ/dt. This is the continuity equation.
