I did not mention the 'third way' to graphically represent voltage, that consists in not using any arrow at all. The polarities '+' and '-' are shown instead. This notation is widely used in American textbooks but has the shortcoming of making it difficult to identify voltages between different branches. But, hey: to each their own. Before reuploading this video I created a poll asking which notation is taught in your country. You can find it in the Community section of the channel if you wish to vote (yeah, I know, I only have a handful of subscribers, but a few is better than nothing, right?)

As a physics student I absolutely love this voltage saga, keep it up!
