Healthy Fats. A classic peanut butter and jelly sandwich has 18 grams of fat. This could be a good chunk of your total daily fat, depending on how many calories you consume. The American Heart Association recommends limiting fat to less than 25 to 35 percent of your total calories.
A rheostat is an electrical device that is used to vary voltage across a network to which it is connected. Since resistance is actually responsible for voltage drop, so by varying the resistance, it is possible to obtain different values of voltage.
Potentiometer vs Rheostat. Potentiometer and rheostat are two components that are used in electronics. Potentiometer is not only used as an electronic component but also a measuring instrument. A rheostat is basically used to vary the resistance of a circuit. These two components are used in both laboratory and industrial purposes.
