Physics A parallel-plate capacitor of capacitance C1 is made using two gold plates. Another parallel-plate capacitor of capacitance C2 is made using two aluminium plates with same plate separation, and all the four plates are of same area. If rg and ra are respectively the electrical resistivities of gold and aluminium, then which one of the following relations is correct? C1pa = C2pg C1 = C2 C2>C1 C1>C2 C1pa = C2pg C1 = C2 C2>C1 C1>C2 ANSWER DOWNLOAD EXAMIANS APP
