Mains Electricity
Mains Supply is AC
- UK mains is supply is approximately 230 volts
- The frequency is at 50 hertz
- AC = Alternating Current
Battery is DC
- DC = Direct Current
- Cells and batteries supply DC
- Current flow in the same direction
Electricity supplies can be shown on an Oscilloscope Screen
- A Cathode Ray Oscilloscope (CRO) is basically a voltmeter
- When you plug an AC supply into an oscilloscope, you will get a 'trace' on the that shows how the voltage of the supply changes with time.
