Example Question #3 : Using Capacitor Equations

Three capacitors of equal capacitance are in a series circuit. If the total capacitance is , what is the capacitance of each individual capacitor?

Possible Answers:

Correct answer:

Explanation:

The formula for capacitors in a series is:

Since we have three equal capacitors, we can say:

Using the value for total capacitance, we can find the value for the individual capacitance.
