On today’s Tech, No Babel: Troubleshooting Techniques: Making the invisible visible

Most of the time, electricity is invisible. If you see a spark, something has gone really wrong, except in rare exceptions. So how can you tell if electricity is flowing? You’ve got to figure out a way to make it visible.

Sometimes it’s as simple as using a special cable. There are cables that light up or have LEDs at one end or the other to show you they’re getting or sending power.

If you’re testing an IR remote, try pulling out your smart phone and shooting the beam into the camera lens. While in camera mode, most of the time, if it’s working, you’ll see blinking on the screen.

Finally, you can use a multimeter to see more information. With the first two tests, you could see if there was electricity, but with a meter, you can see how much, polarity, etc.

We’ll talk more about these devices next week.
