Electronics, Diodes, and Transistors


Part 1: Ohm's Law


  • For this part, you will implement the circuit below on the breadboard and you will measure V1 and V2 (see more information about the voltmeter below). Verify that V1 + V2 = 5 V and that V1/R1 = V2/R2.

  • You may not be able to find a 4 KOhm resistor, but most likely a 3.9 KOhm one. (See chart below, taken from ecee.colorado.edu/~mcclurel.

Measuring Voltages with the Agilent 34401A Voltmeter


AgilentVoltmeter.png


  • Press the DC V button, and plug a black probe (rubber banana plug) into the LO connector (refer to diagram above), and a red probe (rubber banana plug) into the HI connector.
  • Press the Auto/Man button to put the meter into Automatic range measurements.
  • In your lab report, indicate the 3 voltages measured: V, V1, and V2.


Light-Emitting Diodes (LED)


  • Implement the circuit below, which uses an LED. The diagram on the right indicates how to find the polarity of the LED.
  • Connect the input of the circuit (left line) to a Logic Switch. Connect one of the Logic Indicators on the Kit to the same Logic Switch.
  • Comment on your circuit. Is it working the way you want? Why or why not?

  • Fix the circuit by adding the appropriate gate.


Transistor as Inverter


  • Implement the circuit below, using a 2N2222 transistor.
