Worked examples

Electric current and DC 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.

• 1Currents, transported charges and drift velocity
• 2Resistance of wires and temperature dependence
• 3Networks of resistors in series and in parallel
• 4Electric power and the Joule effect
• 5Real sources and maximum power transfer
• 6Multi-loop circuits with Kirchhoff's laws
• 7Charging and discharging capacitors in RC circuits
