The current in the circuit is Zero is true
Define current
An electrical charge carrier flow known as current often involves electrons or atoms lacking in electrons. negative to positive points are crossed by current.
The maximum voltage across the resistor is the first choice. This choice is incorrect because, after a considerable amount of time, the capacity is fully charged and the circuit's current "I" will be equal to zero. Moreover, because current is 0 It will now be equal to zero for the voltage courses resistive "IR."
The next option claims that the voltage across the capacitor is at its lowest. Additionally, this is incorrect because charge across a capacitor reaches its maximum over time. In addition to being maximum, voltage will be maximum and equivalent to charge upon capabilities.
No The capacitor is only partially charged, according to the next option. This is incorrect since it takes a while for the charge to reach its maximum level before the maximum current is claimed. . Which is also incorrect because once the capacitor is fully charged, current eventually zeroes out.
Since the capacitor's charge did not change at all after it reached full charge, the fact that the circuit's current is zero is accurate. Because the charge has achieved its maximum value, the rate of change of charge will be zero, and the current will also be zero.

Solution:
Formula for finding wavelength from frequency is wavelength=wave velocity(c)/frequency(f).
General value of Wave velocity (c) = 3 x 10^8 m/s
Given frequency = 2.0 x 10^6 Hz
Now,
Wavelength = 3 x 10^8 m/s / 2.0 x 10^6 Hz
= 150 m
Therefore the value of wavelength is 150m.
As we know that capacitance of parallel plate capacitor is given as
here we know that the gap between the plates of capacitor is filled by air or vacuum
now if we fill the space between the plates by dielectric medium then we will have
so it will increase the capacitance of capacitor
Also we can see that capacitance is inversely depends on the distance between the plates of capacitor plates
So capacitance will increase if we decrease the distance between two plates
so correct answers are
D) introduce a dielectric material between the plates
E) decrease the separation between the plates
