Measure current, amps, voltage, and resistance in various direct current (DC) and alternating current (AC) energy systems.

Measurement should include

  • using a multimeter
  • configuring the multimeter
  • applying settings to measure
    • voltage (i.e., electrical potential)
    • current (i.e., flow of charge)
    • resistance (i.e., opposition to flow of charge)
  • recording the battery charge and discharge rates in a data table.

Process/Skill Questions:

  • What is the difference among the amps, current, voltage, and resistance measures between a series circuit and a parallel circuit?
  • How do volts change when measuring a series circuit vs. a parallel circuit configuration?
  • How are amps affected in a series circuit vs. a parallel circuit configuration?
  • How does a cell phone or laptop discharge at different rates based on use or settings?
  • How does a lithium-ion battery discharge compare with an alkaline or a dry-cell battery discharge?
  • How is AC safely measured?
