What does Kirchhoff's Second Law state?

• Energy is conserved in electrical circuits.

• Current entering a junction equals current leaving.

• Voltage is constant in a closed loop.

• Power is equal to voltage times current.

How does Kirchhoff's Current Law apply to electrical circuits?

• It states that the total current entering a junction equals the total current leaving the junction.

• It describes the voltage drop across a resistor in a closed loop.

• It indicates that energy is conserved in electrical circuits.

• It applies only to AC circuits.
