==How does a shunt works?==
'''Short:'''<br>
A shunt is a very small resistor that is used to measure current.
The resistor is added in series to the load and the voltage drop is measured.
'''In Detail:'''<br>
The best way to get a better understanding is to have a look at the principle of voltage divider.<br>

This table displays how the resistance value of the shunt (R2) drains power if it is too high.
Also you can see how small the voltage drop gets if the resistance is to low, what makes it hard to measure.
