Ánodo

The video explains the role of the anode in different devices. In power-consuming devices, the anode is positive, while in power-providing devices, such as during electrolysis, it is negative. The anode is connected to the positive terminal of an external power supply and attracts anions, which donate electrons to it.

In a power-consuming device, what is the charge of the anode?

• Variable

• Neutral

• Positive

• Negative

During electrolysis in a power-providing device, what is the charge of the anode?

• Positive

• Negative

• Neutral

• Variable

What is the role of the anode in a power-providing device?

• It attracts anions and receives electrons.

• It provides electrons to cations.

• It repels anions.

• It remains neutral.

To which terminal of an external power supply is the anode connected?

• Variable terminal

• Neutral terminal

• Positive terminal

• Negative terminal

What particles does the anode attract in an external power supply?

• Cations

• Neutrons

• Protons

• Anions
