001 Resistive component multimeter voltage-current-resistance measurements

The simplest circuit is pretty much a single resistive component being powered directly by a regulated power source or battery. Since 5 volt regulated, and adjustable voltage/maximum current supplies are very common, I will therefor be primarily focused on using a supply set to 5V throughout my material.

Simple circuit and multimeter measurement basics tutorial video:

Topics covered.

  • Using a power supply basics.
  • How to measure voltage, current, and resistance of parts of a circuit with a multimeter.
  • Ohms law used to calculate current through a resistor based on it’s resistance and the voltage across it.
  • Tips on keeping a resistive component from overheating based on it’s wattage rating and the power through it. Again, calculated using a power variation of Ohms law.

Using the link above the video to watch it in a new tab is more helpful in letting YouTube and myself know that there is interest in this kind of video than watching the embedded video directly.
