be 7000 and 5000 ohms for R1 and R2 To find the series resistance needed for a 2 volt LED operating from a 12 volt battery at 20 milliamps the values 12 for the battery 02 for the current and 2 for Vout would be entered and the LED would represented by R2 The result should be 500 ohms for the series resistance R1 The calculator can also work problems

every 4 years Under the new rules leap years now occur when the year is divisible by 4 and not 100 or the year is divisible by 400 Thus the years 1600 and 2000 are leap years but 1700 1800 1900 and 2100 are not Under this system the calendar should be accurate within a day for about 3322 years To use the calendar below select a month from the

take a few pieces out and chop them up and mix with chopped green oinions and ginger or whatever other stuff and spices you like Then take out a wonton wrapper and put some of the mixture in the middle Then wet the edges of the wrapper with water so it s soft and fold the wrapper over from one corner to the other so it makes a triangle Then take a little more water on your finger and rub the wonton edges to seal the wrappers Then make another 5 or 6 wonton wraps and fry them all in a pan for a few seconds A few seconds on one side and a few seconds on the other just so they are slightly brown and won t fall apart Might have to add a little oil to the pan so they don t stick Next go back to cooking the chicken and add more water as it cooks so you get a broth with chicken pieces that s enough for the soup I use about 5 cups of water and one chicken thigh with the fat cut off While the chicken is slowly cooking low heat you can chop
