Kirchhoff’s Laws Quiz

1. What does Kirchhoff’s Current Law (KCL) state?

Voltage is constant Sum of currents at a node = 0 Power is conserved

2. Kirchhoff’s Voltage Law (KVL) applies to:

Nodes Loops Resistors

3. KCL is based on conservation of:

Energy Charge Power

4. KVL states that total voltage in a loop equals:

Maximum voltage Zero Current

5. A node is:

A power source A connection point A resistor

6. In LTSpice, how do you measure current at a node?

Use voltage probe Click on a wire Use text tool

7. A node has currents: 2A entering, 1A leaving. What is the missing current?

1A leaving 3A entering 1A entering

8. In a loop, voltages are 10V source and drops of 4V and 6V. What does KVL show?

Balanced loop Extra voltage Missing current

9. In LTSpice, what graph helps verify KVL?

Voltage graph Image Code output

10. If currents into a node equal currents out, the node obeys:

Ohm’s Law KCL KVL
