Voltio (V)

The video explains the concept of electromotive force, which is the potential difference along a conductor with a resistance of one ohm through which a current of one ampere flows. It uses an analogy comparing electric current to water flow, where the electromotive force is likened to the pressure difference that causes water to circulate through a circuit.

What is the definition of electromotive force?

How does the resistance of a conductor affect the flow of current?

What is the relationship between current intensity and electromotive force in a circuit?

If we compare electric current to water flow, what does the electromotive force represent?

Explain how pressure difference in water circulation is analogous to electromotive force.
