Question: If two capacitors of capacitance C1 and C2 are connected in series, what is the equivalent capacitance (Ceq)?

Options:

  1. Ceq = C1 + C2
  2. Ceq = 1 / (1/C1 + 1/C2)
  3. Ceq = C1 * C2
  4. Ceq = (C1 * C2) / (C1 + C2)

Correct Answer: Ceq = 1 / (1/C1 + 1/C2)

Solution: 

The equivalent capacitance for capacitors in series is given by Ceq = 1 / (1/C1 + 1/C2).

If two capacitors of capacitance C1 and C2 are connected in series, what is the

Questions & Step-by-Step Solutions

If two capacitors of capacitance C1 and C2 are connected in series, what is the equivalent capacitance (Ceq)?
  • Step 1: Understand that capacitors in series means they are connected one after the other.
  • Step 2: Know that the formula for finding the equivalent capacitance (Ceq) for capacitors in series is Ceq = 1 / (1/C1 + 1/C2).
  • Step 3: To use the formula, first calculate 1/C1 and 1/C2 separately.
  • Step 4: Add the results from Step 3 together to get (1/C1 + 1/C2).
  • Step 5: Take the reciprocal of the sum from Step 4 to find Ceq.
  • Capacitance in Series – When capacitors are connected in series, the total or equivalent capacitance is calculated using the formula Ceq = 1 / (1/C1 + 1/C2), which reflects how the charge and voltage distribute across the capacitors.
