Basics 01 Current Voltage and electric Power

An analogy between electric and hydraulic power. The analogy shows that you can regard electric sizes in a similar way as hydraulic sizes.

But before we look at that electric system, let's have a look on an hydraulic one:

Quantity, Height and hydraulic Power

The water is pumped up to a certrain height called h. The quantity that flows each second is called Q. Q and h define the power P of these hydraulic wheels.

This way, we can calculate the power that is put into the circuit up and runs the motor.
