Question 1
What does Kirchhoff's Voltage Law state?
- A. The sum of voltages in a loop is zero
- B. Voltage rises are always greater
- C. Voltage drops never equal rises
💡 Hint: Remember the balance of energy in the circuit!
Question 2
In a closed loop, if the total voltage rise is 10V and voltage drops total 10V, does KVL hold?
- True
- False
💡 Hint: Consider the definition of KVL carefully.

Challenge Problems
Push your limits with challenges.
Question 1
A complex circuit includes two voltage sources of 12V and 5V, combined with three resistors of values 10Ω, 15Ω, and 20Ω. Using Kirchhoff's Voltage Law, set up and solve the equation to find the current through each resistor.
💡 Hint: Pay attention to the direction of voltages and resistances when analyzing the loop.
Question 2
Construct a hypothetical circuit with misapplied voltages and demonstrate why KVL fails in this case. What errors would lead to this contradiction?
💡 Hint: Consider how circuit analysis relies on accurate voltage placements.
