Problem 62

Figure 27-64 shows the circuit of a flashing lamp, like those attached to barrels at highway construction sites. The fluorescent lamp L (of negligible + capacitance) is connected in parallel - across the capacitor C of an RC circuit. There is a current through the lamp only when the potential difference across it reaches the breakdown voltage V L; then the capacitor discharges R Fig. 27-64 62. completely through the lamp and the lamp flashes briefly. For a lamp with breakdown voltage VL = 72.0 V, wired to a 95.0 V ideal battery and a 0.150 J.LF capacitor, what resistance R is needed for two flashes per second?

Step-by-Step Solution:
Step 1 of 3

Chapter 28: Physical Optics­ Interference and Diffraction  If two waves occupy the same space, their amplitudes add at each point. They may interfere either constructively or destructively  Conditions for dark fringes (destructive interference) in a two­slit experiment: dsinα = m− 1 λm=1,2,3,… o Above central bright fringe: ( ) 2 1 o Below central bright fringe: inα = ( ) 2 λm=−1,−2,−3,…  Interference is only noticeable if the light sources are monochromatic (so all the light has the same wavelength) and coherent (different sources maintain the same phase relationship over space and time)  Interference will be constructive
