See how a floating magnet in water traces a semicircular path as repulsion and attraction define its motion along magnetic field lines.
Draw magnetic field shapes for a bar magnet, the uniform field between opposite poles with straight, parallel lines, and the repulsion between like poles, using arrows from north to south.
Express charge as the quantity of charge Q, a measurable amount formed by electron transfer; use the coulomb as a larger unit to measure charge, including negative charges.
Explore the electrostatic force on a positively charged particle moving in an electric field between opposite plates, tracing its straight entry, curved trajectory toward the negative plate, and straight exit.
Voltage is the energy per charge moving from the battery to the bulb in a simple circuit, including single-component, series, and parallel arrangements, with v = e/q.
Explore how wire resistance depends on length, cross-sectional area and material, using R = ρL/A; thicker wires reduce resistance, and very short leads can be neglected.
Master the rules for voltage, current, resistance, and power in series and parallel circuits, and apply Ohm's law to past-paper questions.
Compare direct current, flowing in one direction from cells or batteries, with alternating current, which changes direction and is produced by AC generators.
*This Course is about Extended Cambridge (0625) IGCSE Physics… Chapter 3: Electricity,
* This chapter is divided into three courses
Part1: Basic Electricity,
Part 2: Electromagnetism,
Part 3: Electronics,
This course is only part 1 Basic Electricity,
other parts will be in other courses,
*This course covers all the points in the syllabus that are related to Electricity (Part1),
*The course is directed to the point and restricted to the syllabus nothing less and nothing more, so you will not waste your time, with invaluable speech,
* If you know exactly your syllabus you will appreciate these videos,
* The average video duration is 3 mins so you will not get bored with the course and you can find reasonable points to pause and complete later,
* The full course duration is about 1 hours and 43 mins
* This course includes four lessons:
Lesson 1: Magnetism,
Lesson 2: Electrostatics,
Lesson 3: Electric current (Equations and Theoriticls)
Lesson 4: Home Installation,
This course is arranged so that it covers all points about basic electricity,
This course mainly covers the theoretical parts that puts the basics that will help you answer all past paper questions related to Basic Electricity in paper 1 ( the multiple choice), paper 3 (structured questions), and paper 6 ( the alternative to practical),
Lesson 1 Magnetism, this includes bar magnets, magnetic fields, magnetization and demagnetization methods,
Lesson 2 Electrostatics, includes charged bodies, methods of charging, electric field and electric forces
Lesson 3 Electric current is separated into two parts, the first part is the equations, this includes all the equations related to electric current and electric circuits, also explaining the concepts of voltage, current intensity and electric resistance, after that comes the theoretical part which includes definitions, proving ohm's law, the variable resistor, the potentiometer, and electric symbols,
Lesson 4 Home installation, how electricity reaches our homes, some sources of dangers and safety precautions,
