Today we're finding the equivalent capacitance of two capacitors that are wired in series and we can tell these are wired in series because there is no branching in this circuit. There is no option if we are traveling through the circuit. But to pass through c1 and c2 as it go from the high side of the battery to the low side. So part A- asks for the equivalent capacitance of this combination and then we get into some deeper questions about the charge on each capacitor.
The voltage drop over each individual capacitor. We'll go ahead and label everything and when we are simplifying circuits.
We're going to do is simplify a series combination of capacitors to do that we use the formula:
If you calculate the capacitance by that formula, you will the answer 0.542857143 mF. Because here the Cs is the equivalent capacitance. So, the equivalent Capacitance for the circuit of the figure is 0.542857143 mF.
What is Capacitance?
The capacitance of a material is the amount of charge that can be stored on its surface. This can be expressed in Farads (F) or coulombs (C). The S.I. unit of capacitance is the coulomb (C). It is also expressed in Farads (F).
Where do we use capacitors?
Materials with a high capacitance store a large amount of charge. This is why capacitors are used to store energy in electronics. Materials with a low capacitance do not have a lot of room to store charge, and are used in applications like batteries.
