GCSE Physics - Alternating (AC) and Direct Current (DC) #21

The video tutorial explains the differences between alternating current (AC) and direct current (DC). AC constantly changes direction, while DC flows in one direction. UK mains electricity is AC, operating at 50 Hertz and around 240 volts. Direct current is found in batteries and cells. Oscilloscopes are used to visualize voltage changes over time.
