In class we were given 3 pieces of paper outlining how to make circuit stickers. Using a copper wire strip I traced the tape onto the lines. Making corners was difficult but as I practiced my corners became sharper. Next I chose the LED light (either blue, red, or yellow), and stuck them on the traced triangles. After putting the copper tape and LED on the papers, all I had to do was grab a battery and press it between the paper as shown below. I made sure that the positive and negative sides were on the correct outline. In the simple circuit the LED light is between a negative and positive strip that when connected (with the battery) send an electric current around powering the light. In the switch circuit the copper strip opposite of the gap (shown below) controls the light because when folded it completes the circuit. And when unfolded it breaks the circuit. In the parallel circuit there is one negative and open positive strip aligned in a way that when it is connected to a battery each light is reached with energy to power it. In my exploration I had no errors. But I observed in some that when the light wasn't turning on it was usually because of a gap or rip in the wire strip.

QUESTIONS
How do the two circuits (in the second to last paragraph) differ? Why is a short circuit bad? What is the difference between a parallel circuit and a series circuit? |
