Two identical parallel plate air capacitors are connected in series to a battery of e.m.f. 'V'. If one of the capacitor is inserted in liquid of dielectric constant 'K' then potential difference of the other capacitor will become

Options

  1. AKV K+1
  2. BKV K-1
  3. CK+1 KV
  4. DK-1 KV

Correct answer

A. KV K+1

Step-by-step solution

Let the capacitance of each identical parallel plate air capacitor be C . When one capacitor is inserted in a liquid of dielectric constant K , its capacitance becomes C₁ = KC . The capacitance of the other capacitor remains C₂ = C . Since the two capacitors are connected in series across the battery of e.m.f. V , the equivalent capacitance of the circuit is C_ eq = C₁ C₂ C₁ + C₂ = KC C KC + C = KC K+1 . The total charge supplied by the battery is Q = C_ eq V = KCV K+1 . In a series combination, the charge on each
