FAQs on Quick Revision: Electric Charges & Fields - Physics for JAMB

1. What is an electric charge?
Ans. An electric charge is a fundamental property of matter that can be positive or negative. It is responsible for the electromagnetic force and can attract or repel other charges.
2. How are electric charges created?
Ans. Electric charges can be created by various methods, such as friction, contact, and induction. For example, when two objects are rubbed together, electrons can be transferred from one object to another, resulting in the creation of charges.
3. What is an electric field?
Ans. An electric field is a region around an electric charge or a group of charges where another charge experiences a force. It is a vector quantity and its strength determines the magnitude of the force experienced by a charge.
4. How are electric fields calculated?
Ans. The electric field at a point can be calculated by dividing the force experienced by a test charge placed at that point by the magnitude of the test charge. Mathematically, it is given by the formula E = F/q, where E is the electric field, F is the force, and q is the test charge.
5. What is the difference between electric field and electric potential?
Ans. Electric field and electric potential are related but distinct concepts. Electric field represents the force experienced by a charge, while electric potential represents the potential energy per unit charge. In simple terms, the electric field determines the force, while the electric potential determines the work done in moving a charge.
