Study Notes
Electrical Current Types
- Electricity flows as either direct current (DC) or alternating current (AC).
- DC flows in one direction only, shown as a straight horizontal line on a voltage-time graph.
- AC changes direction and size regularly, graphed as a curve alternating between positive and negative voltages.
Direct Current Sources
- Car batteries, dry cells, and solar cells produce DC.
Alternating Current Sources
- Power stations generate electricity using magnets, producing AC.
- The UK's mains electrical supply is AC.
Main Electrical Supply Details
- UK mains supply is 230 Volts (V).
- The frequency of the UK mains supply is 50 Hertz (Hz).
