Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2

My brother, David, was always close to our grandmother. Both of them shared a love of Mother Nature and of food that they had grown themselves. Whenever his schedule permitted, he would drop in for a short visit and a cup of coffee. One day, when he found no one home, he left a chunk of dirt on her porch. This started what was later to be known as his "calling card". Grandmother would come home occasionally and instantly know that Dave had been by when she spotted the chunk of dirt on her porch.

Although Grandmother had a poor upbringing in Italy, she managed to do well in the United States. She was always healthy and independent and enjoyed a fulfilling life. Recently she had a stroke and died. Everyone was saddened by her death. David was disconsolate. His life­long friend was now gone.

David would drop in for a short visit and leave a _____ as a sign on grandma's porch if she was not at home.

A) schedule B) chunk of dirt
C) calling card D) cup of coffee
