Determine the equivalent capacitance for the DC circuit shown in the circuit diagram below if C_1 = 5 μF and C_2 = 10 μF.
Application of Eq. 1.21 to the two-capacitor series circuit shown in the given circuit diagram yields:
C_{EQ}=\frac{1}{\frac{1}{C_1}+\frac{1}{C_2}+\frac{1}{C_3}+…+\frac{1}{C_n}} (1.21)
C_{EQ}=\frac{C_1C_2}{C_1+C_2}\\ C_{EQ}=\frac{(5×10^{-6})(10×10^{-6})}{(5×10^{-6})+(10×10^{-6})}=3.33×10^{-6}=3.33 μF
