, Module 3
Capacitance and Capacitors
What This Module is About
This module showcases your knowledge in Capacitors and Capacitance and critical
problem-solving skills in analyzing capacitors in different network configuration. It also tackles
the fundamental principles of Dielectrics and Capacitor’s Electric Field Energy.
This module has three (3) lessons:
Lesson 1: Capacitance and Capacitors
Lesson 2: Capacitors in Series and Parallel
Lesson 3: Energy Stored and Electric Field Energy in Capacitors
What I Need to Know
After going through this module, you are expected to:
1. Deduce the effects of simple capacitors (e.g., parallel-plate, spherical, cylindrical) on
the capacitance, charge, and potential difference when the size, potential difference,
or charge is changed (STEM_GP12EM-IIId-23)
2. Calculate the equivalent capacitance of a network of capacitors connected in
series/parallel (STEM_GP12EM-IIId-24)
3. Determine the total charge, the charge on, and the potential difference across each
capacitor in the network given the capacitors connected in series/parallel
(STEM_GP12EM-IIId-25)
4. Determine the potential energy stored inside the capacitor given the geometry and the
potential difference across the capacitor (STEM_GP12EM-IIId-26)
5. Describe the effects of inserting dielectric materials on the capacitance, charge, and
electric field of a capacitor (STEM_GP12EM-IIId-29)
6. Solve problems involving capacitors and dielectrics in contexts such as, but not limited
_ to, charged plates, batteries, and camera flashlamps. (STEM_GP12EM-IIId-30)
