Use only the instructor-approved 3 V (2×AAA) pack. Disconnect it before rewiring or changing meter connections. Pause for instructor checks.
Slide 1 of 27
LAB 1 STEP 1 OF 5 SCHEMATIC FIRST
Three parallel branches

Read slide text and tables
Schematic first. Try the connections before opening the next breadboard view.
YOUR STATION
3 V (2×AAA) pack, three 220 Ω resistors, board, meter, jumpers and paper.
UNPOWERED CHECK
Check board continuity and each isolated resistor in Ω. Record R1–R3.
SCHEMATIC BUILD
Connect each resistor between the same positive and negative source nodes.
CHECK
Build with the pack disconnected. Try the schematic before viewing the next slide.
