11.6 Kirchhoff’s Loop Rule

Describe a circuit or elements of a circuit by applying Kirchhoff’s loop rule.

• Energy changes in simple electrical circuits may be represented in terms of charges moving through electric potential differences within circuit elements. Relevant equation:
• Kirchhoff’s loop rule is a consequence of the conservation of energy.
  • i. Kirchhoff’s loop rule states that the sum of potential differences across all circuit elements in a single closed loop must equal zero. Relevant equation:
  • ii. The values of electric potential at points in a circuit can be represented by a graph of electric potential as a function of position within a loop. TOPIC 11.7 Kirchhoff’s Junction Rule
