, What This Module is About
This module demonstrates your understanding on the concepts of Electric
Charges and Electric Field. It specifically discusses about Electric Charges, Coulomb’s
Law, and Electric Forces and Electric Field.
This module will help you explore the key concepts on topics that will help you
answer the questions pertaining to direct-current circuits.
This module has three (3) lessons:
Lesson 1 – Electric Charge
Lesson 2 – Coulomb’s Law
Lesson 3 – Electric Forces and Electric Field
What I Need to Know
At the end of this module, you should be able to:
1. Describe using a diagram charging by rubbing and charging by induction
STEM_GP12EM-IIIa-1;
2. Explain the role of electron transfer in electrostatic charging by rubbing STEM_GP12EM-
IIIa-2;
3. Describe experiments to show electrostatic charging by induction STEM_GP12EM-IIIa-3;
4. Calculate the net electric force on a point charge exerted by a system of point charges
STEM_GP12EM-IIIa-6;
5. Describe an electric field as a region in which an electric charge experiences a force
STEM_GP12EM-IIIa-7; and
6. Calculate the electric field due to a system of point charges using Coulomb’s law and the
superposition principle STEM_GP12EM-IIIa-10
