Voltage Examples
For more complex signals an oscilloscope can be used the measured the dc and or ac voltage for example to measure the voltage across a speaker.
Voltage examples. Electrons create charge which we can harness to do work. Your lightbulb your stereo your phone etc are all harnessing the movement of the electrons in order to do work. These loads cause a voltage dip on the system as a result of the voltage drop in conductors transformers and generators under the high current. This voltage dip can have numerous adverse effects on equipment in the system and equipment and conductors must be designed and sized to minimize these problems.
The voltmeter can measure the dc voltage of a battery for example typically 1 5v or 9v or the ac voltage from the power socket on the wall typically 120v. Electricity is the movement of electrons. Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light.
