EEE4012 Kirchoffs Laws Quiz

Which law is covered in Lecture 1 that determines currents and voltage drops in DC networks?

• Ohm’s law

• Kirchhoff laws

• The superposition theorem

• Norton theorem

In the context of a series circuit, how is the total voltage across the circuit expressed?

• V_tot = V_1 - V_2 - V_3

• V_tot = V_1 * V_2 * V_3

• V_tot = V_1 + V_2 + V_3

• V_tot = V_1 / V_2 / V_3

What does Kirchhoff's Voltage Law (KVL) state about a closed circuit?

• The voltage applied is less than the sum of the voltage drops.

• The voltage applied is equal to the sum of the voltage drops.

• The voltage applied is more than the sum of the voltage drops.

• The voltage applied is unrelated to the voltage drops.

What is a node in a circuit?

• A point where two or more circuit elements are connected together

• A circuit element between two nodes

• A collection of branches forming a closed path

• A single wire with zero resistance

What is a branch in a circuit?

• A point where two or more circuit elements are connected together

• A circuit element between two nodes

• A collection of branches forming a closed path

• A loop with no other loops inside

What defines a loop in a circuit?

• A point where two or more circuit elements are connected together

• A circuit element between two nodes

• A collection of branches forming a closed path returning to the same node

• A single node with one voltage

What is a mesh in circuit terminology?

• A loop that contains no other loop

• A circuit element between two nodes
