Activities

  1. Set up multi-meter. Black probe in COM (common), red probe in V/Z or mA or 10A. Set dial to continuity test. Tap probe tips together. Should hear beep.
  2. Learn to use multi-meter. Dial settings (for manual multimeter) are max values. Can be less than that, but not more. Your turn: Observe what happens if exceed (note signal).
  3. Measure resistor values. Your turn: Observe that a resistor has no polarity (swap the leads).
  4. Measure battery voltages (1.5V) in battery holder, 9V in battery holder. Your turn: Test household batteries to see how flat they are. Your turn: Observe that a battery has polarity.
  5. Prepare a 9V wall source. Wire strippers. Different guage for different wire thickness. Strip outside wire to reveal two thin wires. Strip these. Connect to wall and test voltage. Note polarity. If polarity is positive, then the red wire is +, otherwise opposite. Label with electrical tape so no mistakes.
  6. Light a std LED. Bend the shorter leg at right angles as a convention. This is negative and always goes to the – on the circuit. Get a 1K Z resistor. Follow circuit (resistor on the negative side). Your turn: change colors. Your turn: double the resistance – brightness should dim.
  7. LEDs have polarity. Your turn: What happens if reverse?
