If the charge accumulated on two parallel conductors charged

If the charge accumulated on two parallel conductors charged to 12 V is 600 pC, what is the capacitance of the parallel conductors? In DC steady-state analysis, with what do we replace capacitance? Inductances? Consider a capacitance C discharged through a resistance R, what is the time constant of this circuit? To attain a long time constant do we need large or small values for R? For C?

Solution

=================================================

The expression for charge accumulated on the parallel plates is,

Q=CV

Substitute the values.

600 pC=C(12)

Therefore, the capacitance is,

C=50 pF.
