is. There are several condensers marked as (6uF & 220 V). How manysuch condensers are required to make a condenser marked as (12uF&440 V) ?Ans. 8. |

Answer» For voltage to get 440V from 220V , we need to connect 2 capacitors in series. but, on connecting these 2 in series, the resultant will become Half i.e = 3μF. so, we need to connect 4 rows of 3μF resutant capacitors in parallel to get 4*3 = 12μF capacitance. there total capacitance needed is 4*2 = 8 |
