3.1E-6 is from series. so you add them by 1/C and the answer is 1/c. so for the first one i did 1/8.6E-6 + 1/4.8E-6 = 1/C where C is 3.1E-6
4.1E-6 is also from series. i did 1/6.2E-6 + 1/11.8E-6 = 1/C where C is 4.1E-6.
7.6E-6 is parallel so you just add them. i added 4.1E-6 to 3.5E-6
i did this in three steps. i found C from the first two as a series. then i found c from the top two as a series. then i used my answer from the top two and the lower capacitator as a parallel network. so in the last calculation i did 4E-6. AH! there is my mistake. before i had my old...
For the capacitor network shown in the figure, the potential difference across ab is 12V. Find (a) the total energy stored in this network and (b) the energy stored in the 4.8 uF capacitor.
i first did the leftmost 2 capacitors...
An irregular neutral conductor has a hollow cavity inside of it and is insulated from its surroundings. An excess charge of 16.0 nC is sprayed onto this conductor.
A) Find the charge on the inner surface of the conductor.
B) Find the charge on the outer surface of the conductor.
A point charge 6.50 nC is at the center of a cube with sides of length 0.260 m.
PART A: What is the electric flux through the surface of the cube?
PART B: What is the electric flux through one of the six faces of the cube?
Total flux enclosed by the cube = Q / eo...
A proton is traveling horizontally to the right at 4.20×106 m/s.
Find (a)the magnitude and (b) direction (counterclockwise from the left direction) of the weakest electric field that can bring the proton uniformly to rest over a distance of 3.40 cm.
Part C: How much time does it take the...
