Question
just number 2 please
The large window air conditioner in Anita Breeze's hotel room draws 15 amps of current. The unit runs for 6.0 hours during the course of a day. Determine the quantity of charge that passes through Anita's window AC during these 6.0 hours. Is this charge made up of protons of electrons? How many protons/electrons? 2) A parallel-plate capacitor is made from two aluminum foil sheets, each 6 cm wide and 5 cm long. Between the sheets is a Teflon strip of the same width and length but is 0.45cm thick. (The dielectric constant of Teflon is 2.2). The gap between the top plate and the Teflon strip is 0.35cm thick. a) What is the capacitance of this capacitor? b) Find the magnitude of the charge on each plate when the capacitor is connected to a 12 V battery across pts. a and b. 3.) Find the equivalent resistance of the circuit shown below:Explanation / Answer
C = tA/d
t is the relative permittivity of Teflon
C = k x o x A/d
where k is the dielectric constant of Teflon & o is the permittivity of Vacuum
C = [2.2 x 8.85 x 10^-12 x {6 x 10^-2 x 5 x 10^-2}] / [0.45 x 10^-2]
C = 1298 x 10^-14 F
C = 12.98 pF ...............Ans(1)
Q = CV
Q = 12.98 x 10^-12 x 12
Q = 155.76 x 10^-12 C
Q = 0.155 nC
