Judging from the way the question was asked, a very quick answer is here: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capeng.html . However, note that if you want to bring in dynamical effects, the strict answer depends on how *quickly* the charging happens, and whether any energy is allowed to be dissipated through radiation to the far field (for example, from currents changing in the wires connecting the battery and the capacitor), whether the capacitor is filled with an "ideal" dielectric or something which exhibits hysteresis, and so forth.

Subject: [Phys-l] energy to charge a capacitor and stored energy
I use a 1V battery to charge a capacitor of capacity 1.602x10raised to -19
Farad (1.602x10raised to -19 coulomb is the electric charge of a single
electron).
What is the energy spent by the battery and the energy stored in the
capacitor ?
P.S. If you receive spam mail from my mail id, please report to me. Thanks
