Voltage and current needed to power Blackpool Illuminations
An investigation into voltage and current, using the Blackpool Illuminations as an example. A lot of electrical energy is needed to illuminate all the lightbulbs, with a high voltage (or potential difference) needed to provide the required energy. The voltage gets the electrons moving, while the current is the rate of the flow of the electrons. The higher the voltage we supply, the greater the current used; the greater the current, the brighter the lights.
