Kirchhoff’s Voltage Law (KVL) states that the sum of the voltage drops around a closed loop equals the source voltage.
Task: Click on the voltage drops in the circuit diagram below to add them together and balance the KVL equation.
⚠️ TRAP ACTIVATED: The "One More Drop" Mistake
You clicked the battery (source voltage) and added it to the voltage drops! This is a classic beginner's mistake. KVL says the drops equal the source; you do not add the source voltage in with the drops. Adding all the numbers together incorrectly double-counts the energy in the loop.
✅ Excellent work!
You avoided the trap! You correctly identified that only the resistors are the voltage drops. Their sum (3V + 5V + 7V) exactly equals the 15V source, verifying Kirchhoff's Voltage Law perfectly.
