Using the Breadboard Name______

Purpose

The student will use and understand the breadboard.

Materials

Breadboard

Jumper wires

Christmas lights

Power source

DMM

Voltage + Voltage –

Procedure

  1. Connect a jumper wire from Va to the blue A column. Remember wire must be solid or tinned. NO stranded wire is to be used on a breadboard.
  2. Connect a jumper wire from Vb to the red B column.
  3. Run a jumper wire from A 5 to 5 a.
  4. Run a jumper wire from B 5 to 10a.
  5. Place a light in 5c and 10e.
  6. Attach the 4.5 V power source to Va and Vb.
  7. If the light does not light, check your circuit.
  8. Take three lights and place them in series. Make sure they light.
  9. Draw the pattern on the board above.
  10. Take three lights and place them in parallel. Make sure they light.
  11. Draw the pattern on the board above. Use a different color.

Conclusion

  1. Why are loads placed next to each other on the breadboard?
  1. What happens if you place a light in the same row 5a , 5e?
  1. What happens if you place a light in the same row 5a , 5g?
  1. What is the difference between the last two questions?
  1. Where would you place an IC on the board?
  1. If you place a resistor in 5a and 15a and attach a light in 15c and 25e, where would you place the jumpers to complete the circuit? (Include all needed wires)
  1. Can you place a switch in 6b and 6h and have the switch work properly?
