Practice question

Given: Two capacitors of 15 pF each are connected in series. What is the equivalent capacitance? These values define the system as per NCERT data. Formula: 1/C = 1/15 + 1/15 = 2/15. This is standard NCERT relation. Substitution & Calculation: C = 15/2 = 7.5 pF . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
