情境
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.
這張圖裡有什麼
看懂背後的決策。
01
Use a SPST switch on the positive rail to safely turn the circuit on and off
02
Connect both 1kΩ resistors between the switched supply node and ground to create true parallel branches
03
Use a 0/GND net for the battery return to establish a valid ground reference
Reuse for introductory Ohm's law, Kirchhoff current law, and breadboard wiring exercises where each branch should drop the full battery voltage.
