let electrons flow through it in one direction only. This is very useful in electronic circuits to keep electrons from flowing where you do not want them.Procedure:Assemble the circuit and connect a 9-volt battery to the Battery Snap and observe that the LED is lit, showing that a current is flowing in the circuit. Now, take the Diode out of the Solderless Circuit Board and put it back in with the color band on the opposite end. The LED does not light up.Observations:By doing this experiment, you have seen that the current will flow through the Diode in one direction only. The LED will only light up when the side on the Diode with the color band is connected to the negative terminal of the battery.Conclusion:By completing this Lab you can conclude that the function of a Diode is to conduct current in one direction only.Check Your Work Here a b c d e 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 a b c d e f g h i j 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 f g h i j Here’s What You’ll Need...RESISTORR1hole 12hhole 22e220 Ohm - (Red, Red, Brown, Gold)DIODED1hole 12j Cathodehole 20j AnodeFor the second part of the experiment, put diode in these holesD1hole20j CathodeAnodehole 12j AnodeCathodeLIGHT EMITTING DIODE (LED)LED 1Cathode (flat side)B1hole 23d hole 22dREDBLACKred = hole 23e black = hole 20fSCAN HERE TO SEE MORE ONLINE19AnodeVisit us online at www.ETronCircuit.com for more exciting projectsLAB 10Did you know...Diodes are used in Logic Circuits in computers.
