Question

two identical parallel plate capacitors are joined in series 200 volt battery now a dielectric with K is equal to 4 is introduced between the plates of second capacitor the potential difference on capacitors are​

Answer 1

Answer:

Explanation:

Introducing a dielectric increases the capacitance by K.

Now, charge on both the capacitors is same ⇒CV 1 =4CV2

Also, V1  +V2  =100V⇒5V2 =100⇒V2  =20V V1 =100−20V=80V  

Potential across capacitors =80V,20V
