How to Wire a Parallel Circuit
- 1). Connect the positive battery terminal to a jumper wire. Insert the other end of the jumper wire into a hole in a vertical block of five holes on the breadboard near the end of the breadboard. Insert one lead of the resistor into another hole within the same block and the other lead into the horizontal double row of holes along the top of the breadboard.
- 2). Insert the red LED anode lead --- the lead on the rounded edge --- to the horizontal row of holes along the top of the breadboard. Insert the other lead, the cathode, into the long row of holes along the bottom of the breadboard.
- 3). Insert the green LED anode lead --- the lead on the rounded edge --- to the horizontal row of holes along the top of the breadboard. Insert the other lead, the cathode, into the long row of holes along the bottom of the breadboard.
- 4). Connect the negative battery terminal to a jumper. Insert the other end of the jumper into the bottom horizontal row of the breadboard. The two LEDs will light when the negative lead is inserted into the horizontal row because the two LEDs are wired in parallel with each other.
