Find equivalent capacitance between A and B in the combination given below. Each capacitor is of 2 muF capacitance. |
|
Answer» SOLUTION :The ARRANGEMENT of CAPACITORS can be redrawn as shown in Fig., where `C_1 = C_2 = C_3 = C_4 = C_5 = 2muF`. Capacitane C. for parallel combination `C_2, C_3 and C_4` is : `C.= C_2 + C_3 + C_4 = 2 + 2 + 2 =6muF` Since `C_1,C. andC_5` are in series combination is given by the relation : `1/C = 1/C_1 + 1 /(C.) + 1/C_5 = 1/2 + 1/6 + 1/2 = 7/6 rArr 6/7 muF`
