1. Given three capacitors, C1 = 2.0 F, C2 =1.5 F, and C3= 3.0 F, what arrangement
of parallel and series connections with a 12-V battery will give the minimum
voltage drop across the 2.0-F capacitor? What is
the minimum voltage drop?

2. Suppose three parallel-plate capacitors,
whose plates have areas A1, A2, and A3 and
separations d1, d2, and d3, are connected in
parallel. Show, using only Eq. 242, that Eq. 243 is valid.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
