Today we revised electricity by writing a crib sheet: 8 things I need to know about electricity.
These included: 1) The circuit symbols 2) Current and voltage in a series circuit 3) Current and voltage in a parallel circuit 4) Current-p.d. graphs for resistors, bulbs and diodes 5) Definitions for voltage, current and resistance 6) Common experimental errors 7) The difference between conventional current and electron flow 8) Adding resistors in series |
