Suppose one plate of the capacitor is grounded which means there is charge present at only one plate. We know that the potential across the capacitor will be 0, i.e., V=0. And capacitance of the Capacitor will be C=Q/V. C=Q/0 implying C=∞. So it means that the capacitance of a grounded capacitor is Infinite.
The so-called "resonance", in terms of energy relationship, means that the energy stored in the loop is unchanged and is only converted between the inductor and the capacitor, while the external ...
A system composed of two identical, parallel conducting plates separated by a distance, as in Figure 19.13, is called a parallel plate capacitor is easy to see the relationship between the voltage and the stored charge for a parallel plate capacitor, as shown in Figure 19.13.Each electric field line starts on an individual positive charge and ends on a negative one, so that …
Explanation:When a dielectric slab is introduced between the plates of a parallel plate capacitor, the capacitance of the capacitor increases. The dielectric constant of the material inserted between the plates determines the amount of increase in capacitance.
