If positive potential is applied to the top terminal as shown in Fig. (i), the pn junction on the left will light. Note that the device current passes through the left pn junction. black and decker cordless can opener dave and busters mall of america

"WebThese detect red, green and blue light. The colours we see depend on the different proportions of red, green and blue light which fall on the cone cells. For example, we see yellow when both red and green cones are activated. To produce white light at a point on the screen, all three LEDs are switched on. For black, all three are switched off.
