Question

Two capacitors of capacitance 2 \(\mu\)F and 4 \(\mu\)F are connected in series. The equivalent capacitance is:

• A. 6 \(\mu\)F
• B. 1.33 \(\mu\)F
• C. 8 \(\mu\)F
• D. 2 \(\mu\)F

Hint:

Series capacitors reduce overall capacitance.

Answer 1

The Correct Option is B

For series combination, \[ \frac{1}{C}=\frac{1}{2}+\frac{1}{4}=\frac{3}{4} \Rightarrow C=\frac{4}{3}=1.33\ \mu\text{F} \]
