In this short video Raju understand , what is green house effect and why we feel much hot in a car with closed window ? . Raju is a hypothetical character , which resemble an science student and he has scientific temperament to learn physics in daily life , he is curious about science and physics behind daily life phenomenon . he is gen-z that's why he does not afraid to ask question when he want . still he enjoy every moment of his class and he become funny sometimes . Ujwal Kumar sir is teaching daily life phenomenon in easy way so that every physics students can relate them with physics that he had learnt in the class .

![A parallel plate capacitor is to be designed with a voltage rating 1 KV using a material of dielectr
Question no.2.33- A parallel plate capacitor is to be designed with a voltage rating 1 KV using a material of dielectric constant 3 and dielectric strength about 10^(7) Vm^-1.[Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e, without starting to conduct electrically through partial ionization. For safety, we should like the field never to exceed say 10% of the dielectric strength]. What minimum area of the plates is required to have a capacitance of 50 pF ?
