1. How is the charge stored on a capacitor related to the
capacitance of the capacitor and the potential difference across
the capacitor?
a. The charge equals the product of the capacitance and the
potential difference.
b. The charge equals the ratio of the potential difference to
the capacitance.
c. The charge equals the ratio of the capacitance to the
potential difference.
2. Which do we do to find the potential difference of a
capacitor?
a. integrate the electric field...

capacitor stores 8.0 X 10-9 C of charge at 100V. There are two
metal plates, each of area 1.00 X 10-3 m^2.
a) What is the plate separation in mm?
b) What is the energy stored in the capacitor at 100V?
c) Given that the electric field breakdown is 3.0 X 10^6 N/C,
what is the working voltage of the capacitor?
The question is: How to calculate
the energy of electrostatic field of a newly created
particle.
The usual formula involves integration 'all over space'.
According to GR I believe that 'all over space' means the interior
volume with radius c*t_now, where t_now is the lifetime of the
particle at the time of calculation and c is the light speed.
Thus the energy stored in the field is a quantity dependent on
time evolution.
this is a clarification of the question...
Challenge #1: How is electrostatic force (Felect)
related to the magnitude of charge on the two objects?
Keeping the separation distance for all trials the SAME,
change the magnitude of the charges and record the
force.

charge and FORCE different today than it was yesterday? What type
of relationship is this? Positive/Negative
Linear/Non-linear

By using the principle of energy stored in capacitor, explain
how someone could suddenly experience electric shock.
Can you give me such a long and clear explanations? thank
you
A parallel-plate capacitor has capacitance 8.00 μF. (a) How much
energy is stored in the capacitor if it is connected to a 13.00-V
battery? μJ (b) If the battery is disconnected and the distance
between the charged plates doubled, what is the energy stored? μJ
(c) The battery is subsequently reattached to the capacitor, but
the plate separation remains as in part (b). How much energy is
stored? μJ
