LED Biasing
Purpose:
To light two LED's with a 9V battery with out burning them out. We will use biasing, establishing the correct voltage across and current through a component so it functions properly.
Procedure:
Using V=IR the ideal resistances for the two resistors was determined. After determining ideal values for the resistors we chose the values closest to them from our available standard resistors.
