Two parallel plate capacitors X and Y have the same area of plates and same seperation and air between the plates while Y contains a dielectric medium of in_r=4 Calculate capacitance of capacitor if equivalent of the combind system. |

Answer» SOLUTION :`C_x=(4epsilon_0A)/(d)C = 4 C ` then `C_y=(4epsilon_0A)/(d)C = 4C ` For SERIES combination of Cx and CY `1/C=1/C_x+1/C_y` `implies1/4=1/C+1/(4C)=5/(4C)impliesC=5 MUF` `:.C_x=5muF and C_y=4xx5=20muF` |
