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 electromotive force primarily described as?

• The power consumed by a device

• The current flowing through a circuit

• The potential difference along a conductor

• The resistance in a circuit

What is the unit of resistance mentioned in the context of electromotive force?

• Ampere

• Ohm

• Watt

• Volt

How is the flow of electric current described in the transcript?

• As a magnetic field

• As a current of one ampere

• As a flow of electrons

• As a voltage drop

What analogy is used to explain electromotive force?

• Thermal energy

• Magnetic field

• Light intensity

• Water pressure difference

What does the pressure difference in the water analogy cause?

• Water to evaporate

• Water to flow through the circuit

• Water to boil

• Water to freeze
