Worked examples

Electrical oscillations and AC circuits

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Free oscillations in LC circuits
• 2Resistors, capacitors and inductors in alternating current
• 3Impedance and phase shift in series circuits
• 4Resonance and bandwidth in series RLC circuits
• 5Average power and power factor
• 6Transformers and transmission of electrical energy
• 7Damped oscillations in RLC circuits
