Question 1.
What does Kirchhoff's Current Law state?
Show hintHide hint
Think about a water faucet's flow.
Question 2.
What is the formula for Kirchhoff's Voltage Law?
Show hintHide hint
Consider energy balance in a circuit.
3Question 3.
What does Kirchhoff's Current Law state?
- Total current remains constant
- Total current entering a junction equals total current leaving
- Total current can vary
Show hintHide hint
Remember the water flow analogy.
4Question 4.
Is Kirchhoff's Voltage Law satisfied in a closed loop with equal voltage rises and drops?
- True
- False
Show hintHide hint
Think about balancing electricity in a circuit.
Question 5.
A circuit has two junctions. At the first, 10 Amperes enter when two branches have 4 Amperes and 3 Amperes leaving. At the second junction, 5 Amperes enter. What is the current leaving this second junction?
Show hintHide hint
Apply KCL at both junctions for balance.
Question 6.
Analyze a closed loop with a 24V battery, three resistors dropping 8V, 9V, and one unknown. Find the unknown voltage drop.
Show hintHide hint
Use KVL to check all voltage balances.
