Exam Strategy
📐
Draw circuit diagrams neatly
Every problem needs a circuit diagram. Label all components, currents, voltages. Clear diagram = easier grading = better marks. Use ruler for straight lines.
🔄
Master network theorems
Thevenin, Norton, Superposition, Maximum Power Transfer — guaranteed 20-25 marks. Practice converting between Thevenin and Norton equivalents.
📊
Phasor diagrams for AC
AC problems MUST have phasor diagrams showing voltage-current relationships. Draw to scale if possible. Shows you understand phase relationships.
