  2. Understand how power is created and demonstrated in simple and complex circuits.
  3. Calculate emf, potential difference, equivalent resistance, equivalent capacitance, and power dissipation in a simple and complex circuit.
  4. Analyze and interpret circuit diagrams.
  5. Apply Kirchhoff’s rules in solving complex circuits problems.
