(a)
Whether the given statement is true or false.
(a)
Answer to Problem 1P
The given statement is False.
Explanation of Solution
Introduction:
According to Maxwell's Ampere circuital Law, the line integral of magnetic field along a closed path is equal to
Here,
So, both conduction current and displacement current have same unit.
Conclusion:
Thus, the given statement is False.
(b)
Whether the given statement is true or false.
(b)
Answer to Problem 1P
The given statement is True.
Explanation of Solution
Introduction:
Displacement current developed when atime-varying electric field sets upin a dielectric or capacitor. It was discovered by Maxwell.
According to Maxwell's the expression for displacement current
Here,
So, when
Hence, displacement current only exists if the electric field in the region changing with time.
Conclusion:
Therefore, the given statement is True.
(c)
Whether the given statement is true or false.
(c)
Answer to Problem 1P
The given statement is True.
Explanation of Solution
Introduction:
Displacement current developed when atime-varying electric field sets upin a dielectric or capacitor. It was discovered by Maxwell.
In an oscillating circuit, when the capacitor is momentarily fully charged the value of electric flux is maximum and constant. So, there is no displacement current.
Conclusion:
Therefore, the given statement is True.

The given statement is False.
Explanation of Solution
Introduction:
Displacement current developed when atime-varying electric field sets upin a dielectric or capacitor. It was discovered by Maxwell.
In an oscillating
So, rate of change of electric flux is given by,
Hence, displacement current is given by,
Conclusion:
Therefore, the given statement is False.
