In the figure below, what is the potential difference between the point A and B and between B and C respectively in steady state

Options

A. `V_(AB)=V_(BC)=100V`
B. `V_(AB)=75V,V_(BC)=25V`
C. `V_(AB)=25V,V_(BC)=75V`
D. `V_(AB)=V_(BC)=50V`

Answer

C

Explanation

`C_(eq)=1+(6xx2)/(8)=(5)/(2)muF`
`Q=CV=(5)/(2)xx100=250muC`
`Q_(6)=(3)/(2)xx100=150muC`
`V_(AB)=(Q_(6))/(6)=(150)/(6)=25V`
`V_(BC)=100-25=75V`.
