Basic Electricity

Snap Circuits® uses electronic blocks that snap onto a base grid to build different circuits. These blocks have different colors and numbers on them so that you can easily identify them. Build the circuit shown by placing all the parts with a black 1 next to them on the clear base grid first. Then, assemble parts marked with a 2. Install three (3) “AA” batteries (not included) into the battery holder (B3). 

Set the meter (M5) to the 1A setting.

Turn on the slide switch (S1). The lamp (L4) comes on, and the meter measures how much electric current is flowing.
