Choose a resistor r1 (specify a resistance and power rating as your answer) to be used in the following circuit to illuminate a red led with a vs = 6 v battery. this red led has if = 20 ma and vf = 1.4 v. use the smallest power rating possible for the resistor; you have the following resistor power ratings available: 1/16 w, 1/8 w, 1/4 w, 1/2 w, and 1w. the actual power dissipated by the resistor should not exceed the power rating of the resistor you choose. (you do not need to choose a standard resistance value for the resistor
