Test Voltage, Resistance & Current in a Series Circuit = DC Electronics Topic # 3
Essential to your success in the electronics engineering technology laboratory is to learn the skills of using your DMM effectively that are necessary in measuring physical quantities such as voltage, current and resistance. We begin today’s lesson with “Testing Voltage, Resistance & Current Measurements for Series Circuits in DC Electronics Topic # 3 by the KOGUY.
Most of the theory pertaining to my YouTube Topic videos is very well covered in your assigned textbook for reference BUT I will cover theory for how it can be applied to our hands-on exercises. For now, your primary focus is on “hands-on” training, Why? Because You learn BEST by doing the experiments with your own hands!
Chapters:
0:00 Introduction
1:21 What are voltage, current and resistance
4:29 Electronics Units Table
11:24 Tip for Success = Use a Journal to record key concepts

38:11 AC voltage source examples
41:50 Measuring AC voltage sources
54:00 Measuring resistance
1:12:50 DMM test leads alternatives
1:16:50 Measuring current, DMM and breadboard setup
1:21:27 Building circuit onto breadboard
1:26:20 Measuring current on the breadboard
1:39:00 Accident = touched RED probe of ammeter to Vs, never use probe as a pointer
1:41:10 Replacing blown ammeter fuse in DMM
1:46:30 Test ammeter function after fuse replacement
PLEASE NOTE: My DMM fuse blew out at the 1hr 38 minute time mark as I inadvertently used the RED DMM probe as a "pointer" during describing different part of the series circuit on the breadboard and accidentally touched the RED power rail jumper wire while the BLK DMM probe was still connected to the negative side of the OPEN, Ooooops! Glad it happened though as it allowed me to show the step-by-step process of changing an accidentally blown DMM fuse!
