MediumDescribe the research conducted by scientists regarding electricity and magnetism following Oersted's observation.
(N/A) Following Oersted's observation, scientists conducted significant research:
In $1864$, the laws governing electricity and magnetism were unified and formulated by James Clerk Maxwell, who subsequently realized that light consists of electromagnetic waves.
Radio waves were discovered by Heinrich Hertz and were later produced by $J. C. Bose$ and $G. Marconi$ by the end of the $19^{th}$ century.
A remarkable scientific and technological progress occurred in the $20^{th}$ century, primarily due to an increased understanding of electromagnetism and the invention of devices for the production, amplification, transmission, and detection of electromagnetic waves.

View Solution$A$ parallel-plate capacitor with circular plates is being discharged. The radius of the circular plates is $10 \ cm$. $A$ circular loop of radius $20 \ cm$ is concentric with the capacitor and located halfway between the plates. If the electric field between the plates is changing at the rate of $3.6 \times 10^{12} \ V/(m \cdot s)$,then the displacement current through the loop is (Assume $\frac{1}{4 \pi \varepsilon_0} = 9 \times 10^9 \ N \cdot m^2/C^2$) (in $A$)
$A$ parallel plate capacitor is completely immersed in a liquid of resistivity $\rho = 0.25 \, \Omega m$ and relative permittivity $\epsilon_r = 80$. If the plates of the capacitor are connected to an alternating voltage source of $V = V_0 \sin(\omega t)$ at a frequency of $f = 0.4 \, GHz$,then the ratio of the amplitudes of the displacement current $(I_d)$ and conduction current $(I_c)$ is:
