Answer's D?

 

[funky brat]

nhi aya samjh

Capacitor ko charge honay ka liye 110 v chahye. Agar use kam milen gey to wo dair se charge ho ga.

 

[kirann]

somebody explain this ... waiting..

 

[kirann]

Answer's D?

yes

View attachment 42974 yeh kia bolre hein???????????

A capacitor is charged by connecting it to a DC (direct current) supply. As charge is stored, the voltage across the capacitor gradually increases to a maximum. The maximum voltage is the same as the voltage of the supply.

Resistance is Inversely Proportional to Current

If you increase the resistance the current flowing in the circuit will become less so charging of the capacitor will take more time to charge.
More time taken means that lamp will be on for a long time. So B

volume double means pressure half so presure becomes 100 and then add atmospheric pressure to it.
