JAMB Physics 2015 Objective — Question 11

Question 11 of 50 from the Joint Admissions and Matriculation Board (JAMB) Physics 2015 Objective paper, with the correct answer and a full explanation.

In the diagram, three 3μF capacitors are connected in series. What is the equivalent capacitance?

• A. 1/3μF
• B. 1/2μF
• C. 1μFCorrect
• D. 3μF

Explanation

For capacitors in series, 1/C = 1/3+1/3+1/3 = 1, so C = 1μF.
