If a dc source of 7V is connected across AB, how much charge is drawn from the source and what is the energy stored in the network?

Explanation

Calculation of charge and energy stored
Charge drawn from the source
`Q=C_(eq)V`,
`=6/7xx7muC=6muC`
energy stored `=U=(Q^(2))/(2C)=(6xx6x10^(-12)xx7)/(2xx6xx10^(-6))J`
`=6//7muF`
