A voltage is induced across an inductor (back EMF), that is equal to the product of the inductor's inductance and the rate of change of current through the inductor. All circuits have, in practice, some inductance, which may have beneficial or detrimental effects.
Plan on using 5 to 10 pounds of dry ice for every 24-hour period depending upon the thickness of the insulated shipping container.This will keep everything frozen in a container up to 15 quarts. For larger containers and greater shipping times multiply dry ice quantities by this rate.lan on using 5 to 10 pounds of dry ice for every 24-hour period depending upon the thickness of the insulated shipping container.
The best/only way I have found to hard cook fresh--1 or 2 day old eggs--that allows for them to be peeled cleanly, is to steam, not boil them. Put eggs in a basket over about 2 of water. Bring to a boil, cover and cook on medium heat so steam continues for about 20 minutes. Prepare an ice water bath as eggs steam. At the 20 minute mark remove basket and put basket with eggs in the ice water. Peel them in the ice water.
