Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

A typical AA size rechargeable NiMH battery
can store 1100-2100 mAh of electric charge.
The small print on the battery in your hand
says 1530 mAh. Can you express this amount
of electric charge using the usual coulomb
units?
You are now charging a camera battery. The
charger moves 4470 C of electric charge from
the negative terminal of the battery to the
positive terminal. (In reality the charger
moves the negative electrons from the
positive terminal to the negative terminal, but
this is not important for us right now.)
Assuming - incorrectly - that the voltage of
the battery remains a constant 3.20 V during
the whole charging process, determine the
work done by the charger.
And now you are charging a capacitor bank
for a high-voltage physics experiment. The
power supply moves Q = 8990 C of electric
charge in the charging process. The supply is
set to stop, when the voltage reaches AV =
710 V. How much work did the power supply
perform?
