Kirchhoff’s Laws

Physics ⇒ Electricity and Magnetism

Kirchhoff’s Laws starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Kirchhoff’s Laws. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A circuit consists of a 10 V battery and two resistors (5 Ω and 5 Ω) in series. What is the current in the circuit?
A circuit has a battery of 9 V and two resistors of 3 Ω and 6 Ω in series. What is the voltage drop across the 6 Ω resistor?
A circuit has a junction where 3 A enters, 2 A leaves, and I leaves. Find I.
A circuit has a loop with a 24 V battery and three resistors (4 Ω, 4 Ω, and 8 Ω) in series. What is the current in the loop?
A circuit has three branches at a junction: I₁ = 2 A entering, I₂ = 1 A leaving, I₃ = ? (leaving). Find I₃.

In a circuit, if the sum of EMFs in a loop is 15 V and the sum of potential drops is 12 V, what is the sum of the remaining potential drops or rises in the loop?
In a circuit, three wires meet at a junction. If 2 A flows in from the first wire, 3 A flows in from the second, and the third wire carries current out of the junction, what is the current in the third wire?
