Activity: Rectification
Conduction occurs in semi conductors, which operate via PN junctions. You'll become able to sketch the I-V curve for a PN junction, draw circuit diagrams for full wave and half wave rectifiers and deduce output for diode bridges. Doing this at home? You'll struggle to build bridges on PhET, but Paul Falstad's circuit simulation will enable you to try rectification for yourself: Rectifier simulation (Falstad)...
