Voltage and current
The document discusses the differences between currents and voltages in electrical circuits. It uses analogies of water flowing through pipes to explain currents, which refer to the amount of electrons passing through a wire, and voltages, which refer to the "pump" pushing electrons through the wire. A higher voltage results in electrons moving faster through the wire, similar to how a stronger pump pushes water faster. It also briefly mentions Ohm's law and units of resistance.

The presentation initiates a discussion about electrical concepts, humorously contrasting 'currents' with 'currant'.
Currents are compared to water in a pipe, highlighting how electrons flow through wires, illustrating the concept of electrical current.
Voltage is likened to a pump pushing water, indicating how higher voltage increases electron flow through a wire.
Introduction of the Ohm as the unit of resistance, underscoring its importance in assessing electrical circuits.
The presenter concludes with a light-hearted note, hoping the audience has learned about electrical concepts.

Voltage and current
- 1. Aren’t they thesame?
- 2. NO! Let us begin with currents! NO!!! Not this type of currant! That’s with an A, various forms include red and black!
- 3. Currents They are often described as water in a pipe! The pipe imitates the wire The water imitates the electrons The current (or the amplitude) is the amount of electrons passing through the wire.
- 4. Voltage The voltage is often described as the pump at one end of a pipe. The harder the pump pushes, the faster the flow of water through it. The higher the voltage, the faster the electrons are passing through the wire!
- 5. EXTRA KNOWLEDGE OHM-Y GOLLY GOSH!!!! The OHM is the unit that the amount of resistance in a circuit is measured in!!
- 6. FINISHED I hope you have learnted! :D
