The main differences between emitter and collector are doping concentration and size. The emitter is heavily doped, while the collector is lightly doped. You could try to swap them, but you'll get a very low \$H_{FE}\$, probably even less than 1.

Size and color vary widely among types, but the eggplant should feel heavy. Avoid those with wrinkled skin, soft spots, or brown patches.
Planting â The most common way to plant eggplant is to transplant them, starting them as seedling inside 6-10 weeks before planting. Eggplants really do well in warm weather, and are very intolerant of frost. They need full sun (at least 6-8 hours of sun a day).The soil pH should be 5.5 to 6.5.Donât plant any sooner than 1-3 weeks after the last frost date. Soil temperatures of 65 ot 85 degrees are needed for germination, and even warmer air temperature of 75 degrees is best for growing eggplant. The plants spread a lot, so space them 18 to 24 inches apart.he soil pH should be 5.5 to 6.5. Donât plant any sooner than 1-3 weeks after the last frost date.
