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.

Explain the significance of the anode being positive in a power-consuming device.

What type of ions does the anode attract, and what do they provide?
