11 How do manufacturers construct capacitors? O By placing two conducting plates separated by an insulator By placing two conducting plates separated by a conductor. By placing two insulating plates separated by an insulator. By placing two insulating plates separated by an conductor

Two thin plates (0.50 m x 0.50 m x 'very thin') of a parallel capacitor are located parallel to the xzplane. One of the large plates crosses the y-axis at y = 0 cm, and the other crosses at y = -1 cm. The charge on the positive plate is +30 nC, and on the negative plate, -30 nC. a) What is the voltage from the positive plate to the negative plate? b) What is the electric potential difference from the negative plate to a point in the middle of the space between the plates? c) If the electric potential at the negative plate is 100 V, what is the electric potential at the positive plate? ( d-f) The negative plate is now shifted 0.5 cm away from the positive plate. d) What is the voltage from the positive to the negative plate? ( e-f) If an electron is released from rest from very close to the negative plate, and it flies to the positive plate, e) what is the electron's change in potential energy? f) what is the electron's speed when it hits the positive plate?

#16 Does the charge that flows into the capacitor during the charging go all the way through the capacitor and back to the battery, or does it get stored somewhere in the capacitor?  a It goes all the way through the capacitor and back to the battery.  b It gets stored somewhere in the capacitor.

2) The capacitances are C₁ = 1.0 mF and C₂ = 3.0 mF, and both capacitors are charged to a potential difference of V = 100 V but with opposite polarity as shown. Switches S₁ and S₂ are now closed. a) What is now the potential difference between points a and b? b) What now is the charge on each capacitor? G a Sq

II Review A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.70 cm wide and 12.0 m long. Between the sheets is a mica strip of the same width and length that is 0.0225 mm thick, Part A What is the maximum charge that can be stored in this capacitor?
