Electricity & Electromagnetism
A-Level Physics Electricity & Electromagnetism Tutor
Electricity and Electromagnetism is one of the most mathematically rich parts of A-Level Physics. From Kirchhoff's laws and capacitor charging to Faraday's law and transformer design, students need both formula command and deep conceptual understanding. Our tutors are specialists in all A-Level exam boards.
Board: Cambridge A-Level / AQA / OCR / Edexcel
Topics Covered
- Electric fields and potential
- Capacitance and capacitor charging/discharging
- Kirchhoff's current and voltage laws
- Resistance and resistivity
- Magnetic flux density and force
- Electromagnetic induction (Faraday & Lenz)
- Transformers and AC circuits
- Hall effect (some boards)
Exam Tips
- Tip 1:Capacitor charge: Q = Q₀e^(-t/RC) — know the time constant τ = RC
- Tip 2:For EM induction: induced EMF = -dΦ/dt (Faraday's law)
- Tip 3:Lenz's law: induced current always opposes the change that causes it
- Tip 4:For AC circuits: Vrms = Vpeak/√2
