Question

A capacitor of unknown capacitance is connected across a battery of v volt.the charge stored in it 360micro coloumb .when potential across the capacitor reduced by 120vthe charge stored in it becomes 120micro coloumb .calculate the potential v of the unknown capacity


c.and what will be the charge stored in the capacitor .if the voltage applied had increased by 120v

Answer 1

=the cpester is charged up to 360 micro
= the charged wet Is 120plus 120
