The Parallel Load That Tripped the Supply
Adding a parallel branch does not simply split a fixed source current. Investigate why a source protected at 3 A trips when a second load is connected.

The Voltage Divider That Collapsed Under Load
A divider can be mathematically correct when unloaded and still miss its target once a finite load is connected. Diagnose why 6 V falls to 4 V.
The Circuit That Shouldn’t Have Burned
A correct current calculation does not guarantee a safe resistor. Investigate why a 2 ฮฉ resistor fails in a 12 V circuit even though Ohm’s Law checks out.
