How do we know how strong the electric currents in space are?
What kind of instrument is used ..... ?

Re: measure electricity
When electrical currents are strong enough, they can produce light.
The strength and colour of the light depends on the medium and strength of the current.
The colour/frequency of the electric light can reach from infrared/heat (think of an electrical heater)
to x-rays/gamma-rays (think of an x-ray machine).
In the produced light, we can also see the Zeeman effect.
https://en.wikipedia.org/wiki/Zeeman_effect
The Zeeman effect shows how much magnetism is present, and we
can guess the strength of currents from the magnetism.
This effect is similar to the Stark effect for electrical fields,
so there is some confusion sometimes.
Magnetism can also cause rotation of the polarisation,
https://en.wikipedia.org/wiki/Faraday_effect
or even cause polarisation.
These effects can also be caused by static electric fields.
Currents in an external magnetic field, move in a spiral.
This movement is reduces the present magnetic field, so a current can not
produce its own magnetic field.
This produces synchrotron radiation.
https://en.wikipedia.org/wiki/Synchrotron_radiation
The currents can also cause movement of the ions in the plasma, which then
also move neutral atoms. This is what we can see in plasma-lines on the sun.
The electric currents themselves need to be driven by electrical fields.
These can be caused by differences in electric charges,
or by the movement through external magnetic fields (which are then reduced).

Re: measure electricity
We don't know what electric current is.
How could we judge how strong it is?
There are some empirical evidences, but will those criteria work under any circumstances?
It's a lot of research on electric current should be done here, on Earth.
Current is driven by something else, not by electric field.
In the vicinity of Earth the electric field equals to approx. 100 V/m.
Never saw current flow in vertical conductor.
I have a strong feeling that electric current somehow connected to the aether motion.
