Blowing Things Up

A favorite lesson of Alicia’s in the BTU Lab is why you need resistors. On a regular basis she teaches students why resistors are important by showing them that an LED will burn out with a 9v battery (and no resistance). Today’s demonstration was especially explosive! This LED blew it’s top!

This has been a public service announcement to use resistors!

Why we use resistors!
The LED on the left used a resistor, the LED on the right blew up.
