How many `6muF, 200V` condensers are needed to make a condenser of `18muF, 600?`A. 9B. 18C. 3D. 27 |
Answer» Correct Answer - D In series arrangement, potential difference is the sum of the individual potential difference of each capacitor. `"i.e. "V=V_(1)+V_(2)+V_(3)+…` `therefore" "600=x xx 200` x = 3 So, there should be 3 capacitors in series to obtain the required potential difference. The equivalent capacitance of the 3 capacitors in series is `(1)/(C_("eq"))=(1)/(6)+(1)/(6)+(1)/(6) rArr C_("eq")=2` |
