Question

61. Two identical parallel plate capacitors are joined
in series to 100 V battery. Now a dielectric with
K = 4 is introduced between the plates of second
capacitor. The potential difference on capacitors are
1) 60 V, 40 V
2) 70 V, 30 V
3) 75 V, 25 V
4) 80 V, 20 V​

Answer 1

Answer:

PLS MARK ME THE BRAINLIEST

Explanation:

3) 75V , 25 V

After inserting a dielectric plate C1 =3C and C2  =C

V1 =  3C+C C×V = 4C C×100  =25V,V  2=100−25=75V

Answer 2

Answer:

80V 20V

Explanation:

V1=c2*v/(c1+c2)=4C*100/5C=80V

v2=c1*v/(c1+c2)=20V
