Question 1.
Explain Kirchhoff's Current Law.
Show hintHide hint
Think about how charge is conserved.
Question 2.
What does Kirchhoff's Voltage Law state about a closed loop in a circuit?
Show hintHide hint
Consider the energy input and output.
3Question 3.
What does Kirchhoff's Current Law state?
- The sum of currents is always positive
- The sum of currents at a junction is zero
- The total voltage in a circuit is positive
Show hintHide hint
Think about how currents behave at a junction.
4Question 4.
True or False: Kirchhoff’s Voltage Law states that the total voltage in any loop must equal the voltage of the sources.
- True
- False
Show hintHide hint
Consider the relationship of voltage drops and gains.
Question 5.
Create a circuit diagram with two branches, applying KCL and KVL to find unknown currents and voltages.
Show hintHide hint
Make your equations based on the flows of current and the voltage drops in your diagram.
Question 6.
Given a circuit with a 12V source, a 3A current flowing into a node, and two paths leading out: one path with 2A and another unknown. Calculate the unknown current using KCL.
Show hintHide hint
Remember to set up your equation based on flows at the junction.
