Dear aspirant,

It's very important to choose between packages and interest. Nowadays, it is the bitter truth that if you have money ,the world is under you and yes I do agree in some cases money also fails but it is good to have money.

Coming to your question ,

A transformer by itself can change the voltage of a signal but does not change the amount of power. For a given increase in voltage, there is an equivalent decrease in the current.  The power remains constant.   In fact due to resistive losses the amount of power is actually a

hi,

you did not give the circuit details, whether the capacitors are in parallele or in series. suppose the two  capacitor c1, c2 are in series than equivalent will be

equivalent for two series capacitor=(c1*c2)/(c1+c2)

if the capacitor are in parallel then equivalent is =c1+c2.

capacitor rules is opposite to
