CASE ANALYSIS

Scenario

A basic electronics lab setup tests current and voltage distribution in a parallel resistive branch using a 9V battery and two 1kΩ resistors on a breadboard.

Key decisions

  • Use a SPST switch on the positive rail to safely turn the circuit on and off
  • Connect both 1kΩ resistors between the switched supply node and ground to create true parallel branches
  • Use a 0/GND net for the battery return to establish a valid ground reference

When to reuse this

Reuse for introductory Ohm's law, Kirchhoff current law, and breadboard wiring exercises where each branch should drop the full battery voltage.
