Capacitors: JAMB Physics Past Questions and Answers

What the JAMB syllabus covers in Capacitors

Our summary: How capacitors store charge and energy and what sets their capacitance.

• Types and functions of capacitors
• Parallel plate capacitors
• Capacitance of a capacitor
• The relationship between capacitance, area, separation of plates and medium between the plates ($C = \frac{\varepsilon A}{d}$)
• Capacitors in series and parallel
• Energy stored in a capacitor

Objectives

• determine uses of capacitors;
• analyse parallel plate capacitors;
• determine the capacitance of a capacitor;
• analyse the factors that affect the capacitance of a capacitor;
• solve problems involving the arrangement of a capacitor;
• determine the energy stored in capacitors.
