D861 Electricity and Magnetism is part of Western Governors University's secondary physics route.
WGU's program guidebook describes a comprehensive exploration of the fundamental principles of electricity and magnetism, applied to real technologies such as electronics, motors and infrastructure, to prepare future physics teachers.
The ideas are abstract because you cannot see fields or current, so students lean on analogies and diagrams. The usual trouble is switching between concept and calculation: knowing why current splits in a parallel circuit and also computing the values correctly.

What D861 Covers
An earlier edition of WGU's guidebook lists three competencies for this course; the themes below follow them. Confirm current details on your course page.
| Theme | What it means in practice |
|---|---|
| Electric charges, forces and fields | Coulomb's law, field patterns and potential |
| Electric circuits | Voltage, current, resistors and capacitors in combinations |
| Magnetic fields and forces | Fields, forces on moving charges |
| Electromagnetic induction | Changing magnetic flux producing voltage |
| Applications | Motors, generators, electronics and the power grid |
Key Concepts Explained
Series and Parallel Circuits
In series, the same current flows through each resistor and resistances add. In parallel, each branch has the same voltage and currents add. Parallel branches lower the total resistance.
Example: A 6 ohm and a 12 ohm resistor are in parallel across 12 V. Branch currents: 12 / 6 = 2 A and 12 / 12 = 1 A, total 3 A. Equivalent resistance = 12 / 3 = 4 ohm, smaller than either resistor.
Force on a Moving Charge
A charge moving in a magnetic field feels a force at right angles to both velocity and field. Because the force is sideways, the charge follows a curved path and its speed does not change.
Example: Explain why a magnetic field cannot speed up a moving charge. The force is perpendicular to the motion, so it does no work; it only changes direction.
Faraday's Law of Induction
A changing magnetic flux through a loop induces a voltage. Moving a magnet into a coil, or rotating a coil in a field, produces a current. That is how generators work.
Typical Assignments and How to Approach Them
WGU's guidebook does not list task prompts. The table describes kinds of work this content points to. Follow your own instructions.
| Work type | What it tests | How to approach it |
|---|---|---|
| Circuit analysis | Applying Ohm's law and combinations | Redraw the circuit and simplify step by step |
| Field and force problems | Direction and magnitude | Sketch directions first, then compute |
| Induction explanation | Concept and cause | State what changes and why current results |
| Applied explanation | Linking theory to technology | Pick a device and trace the physics |
A Study Approach That Works
- Start with charge and field. Draw field lines until they feel natural.
- Move to circuits. Practice series, parallel and mixed networks.
- Add magnetism. Use right-hand rules consistently.
- Finish with induction. Connect it to a generator you can describe.
Where Students Get Stuck
- Theory without application. The course emphasizes real technology, so connect each idea to a device.
- Direction mistakes. Right-hand rules fail when applied inconsistently.
- Series versus parallel. Check which quantity is shared.
- Sign confusion with induction. State what the induced current opposes.
Planning Table
| Stage | Goal | Evidence to keep |
|---|---|---|
| Read the task | List requirements | Rubric checklist |
| Diagram | Draw circuit or field | Labeled sketch |
| Solve | Apply laws with units | Worked steps |
| Interpret | State what it means | One sentence |
| Apply | Link to a device | Short example |
Self-Check Questions
Work through these questions with a sketch for each.
- What happens to total resistance when you add another resistor in parallel?
- In which direction is the force on a positive charge moving through a magnetic field?
- Why does moving a magnet into a coil produce a current?
- How does a generator turn motion into electrical energy?
- Which everyday device depends on each of the ideas above?
Study Tips for D861
- Redraw every circuit cleanly before solving.
- Write which quantity is shared in each network.
- Use the same hand rule every time and check with a quick sketch.
- Estimate before calculating.
- Link each topic to something in a home or car.
