**Tension** It is the difference in height that exists between the two highest and lowest points for a waterfall. The water will flow in that direction. This notion is clearer when it is called Potential Difference (DDP). Electrons only circulate if there is DDP. It takes a high potential (the + of the battery) and a low potential (the - of the battery) for electricity to flow. We measure in Volts. **Tension** It is the difference in height that exists between the two highest and lowest points for a waterfall. The water will flow in that direction.

**Intensity** This is the amount of water that will flow in a given time. For example, one liter per second. The stronger the PDD and the lower the resistance, the higher the intensity will be. We measure in Amps. **Intensity** This is the amount of water that will flow in a given time. For example, one liter per second.

**Inductance and Capacity** are interesting but require more knowledge.

### 1. What are all these symbols?
There are plenty of components that all have a symbol, and some even have multiple symbols depending on the cultures and specifics of the component. There are plenty of components that all have a symbol, and some even have multiple symbols depending on the cultures and specifics of the component.
