Capacitors Questions:

Question #1:

What is the magnitude of the force that the electron feels, is the left plate negatively or positively charged?

An lepton is placed between the plates of a live capacitor. The plates have a possibleness of 2500V. The distance between the plates is 2 cm. a In which direction will the lepton see a force? b What is the ratio of the force that the electron will feel? c Is the left plate negatively live or positively charged?

Question #2:

Physics capacitor, charge problem?

An drained capacitor is adjoining to the terminals of a 3.0 V battery, and 6.0 μC flows to the constructive plate. The 3.0 V shelling is then garbled and replaced with a 5.0 V battery, with the positive and negative terminals connected in the aforementioned manner as before. How such added charge flows to the positive plate?

Serious answers only please!!

Question #3:

Physics electric field, capacitor problem?

The automobile field capableness is 20,000 V/m inside a parallel-plate condenser with a 1.0 mm spacing. An lepton is free from rest at the perverse plate. What is the electron's speed when it reaches the positive plate?

Serious answers only, junk answers module be flagged. More than one answer appreciated too. Thanks!!

Question #4:

Rating capacitors...?

Two capacitors are rated at 4.7uF. However, digit says 10V while the other says 16V. If they hit the aforementioned capacitance, shouldn't they hit the aforementioned voltage rating?
Also, does this mean one capacitor can accumulation more charge than the other?

Question #5:

Which of these are good for the working class?

B.L.S. accumulation shows we should wait the mass if we add more Democrats to D.C.

Question #6:

A 1.4-µC point charge is placed between the plates of a parallel plate capacitor.?

A 1.4-µC saucer calculate is settled between the plates of a parallel plate capacitor. The charge experiences a obligate of 0.72 N. What is the ratio σ of the calculate spacing on either plate of the capacitor?

I'm disagreeable to study for my test and my aggregation is online and I cant seem to encounter the answers anywhere. I meet poverty to make sure I am doing this right before my test. PLEASE HELP.

Question #7:

850 V is applied to a 2100 pF capacitor. How much energy is stored?

Question #8:

Physics, Finding the charge on the surface of the capacitor.?

I need whatever counselling as to how I crapper solve this problem. Thanks for your help.

Question: An empty condenser has a capacity of 4.22 10 -6 F and is connected to a 12 v battery. A stuff material k = 4.5 is inserted between the plates of this capacitor. What is the ratio of the opencast charge on the dielectric that is adjacent to either bag of the capacitor? the surface charge is coequal to the disagreement in chare on the plates with and without the dielectric.

Known: blank condenser as Co = 4.22 x 10 -6 F; potential difference, V= 12V; stuff constant, k= 4.5; uncharted is charge, q.

I used equation q= k Eo A/d V is aforementioned as q= CV

and C = kCo; both k and Co are known values. C= 4.5 4.22 x10 -6 F = 1.9 x 10 -5 F.

then q = CV so q = 1.9 x 10 -5 F 12V = 2.28 x 10 -4 C. and was wrong....if you would point discover the mistakes I made, it would help me rattling much. Thank you.

Question #9:

Battery with Parallel capacitor?

An AA battery is adjoining to a parallel-plate capacitor having 7.69 cm diam plates distributed 1.24 mm apart. How much charge in C does the battery cater to apiece plate?

Question #10:

Physics; finding dielectic constant, k?

I am not sure if I am intellection and treating a problem the correct artefact to solve. I appreciate your help, thank you.

Question: Two capacitors hit the aforementioned separation, but digit has square plates and the another has broadside plates. The square plates are a length L on each side, and the diameter of the broadside plate is L. The capacitors have the same capacity because they contain assorted dielectric materials. The dielectric constant of the material between the square plates has a value of k squae = 3.6. What is the k circular of the material between the circular plates?

To find constant k, I used C = k Eo A /d. and rearranged it to -->k = d C/ Eo A for the question.
For A, Atlantic of conservativist is 2L, and broadside is pi 3.14 r 2 , so is pi sq.rt L for this circular area?
anyhow, capacitance C on both is the same, so as long as finding one C, I should apply it to the k ciruclar = d C / Eo A. I do not know how to encounter Eo from given infomation. Help please!
