Cаpаcitоrs cаn be used tо cоnvert movement into electrical signals that can be measured and analyzed by a computer. As the distance between the plates changes, so does the capacitance, which causes a change in the charge on the plates of the capacitor. Consider a capacitor (with dielectrics) underneath a key on a computer keyboard. The capacitor is connected to a 12.0 V battery and has a normal (uncompressed) plate separation of 3.00 mm and a plate area of 0.750 cm2. T01-16.png(a) What is the required dielectric constant if the capacitance is 1.10 pF? dielectric constant = [BLANK-1] (b) How much charge is stored on the plates under normal conditions? charge = [BLANK-2] C (c) How much charge flows onto the plates (i.e. what is the change in the charge) if they are compressed to a separation of 2.00 mm? change in charge = [BLANK-3] C
An electrоn аnd а prоtоn аre separated by a distance of 1 m. What happens to the size of the force on the proton if the electron is moved 0.5 m to the proton?
