As you can see now, the voltage not very high, but of course, we
just need to turn on the light and it'll start producing, so let's do that.
So now we can see the solar cell in this case, is producing four volts.
And, then what we then can do of course
is, we can look at what is happening this situation.
What has happening is we connected a voltmeter.
And a voltmeter has an almost infinitely high resistance.
So that means no current is running through the, the voltmeter.
At least in an ideal case.
And that means that voltage we are measuring right now,
is the maximum voltage that the solar cell can produce.
We can also look at the current we can measure in this way.
It's called the Isc, so that stands for short circuit current.
And what happens there is we would turn the knob
on the multimeter so it goes into the current range instead.
In that case, we would have a, almost all
of the current that the solar cell could be producing.
Or, in an ideal case, all of the current that the
solar cell is producing will run through the multimeter and
when that happens, you get the maximum current that the solar
cell can produce and that's called Isc or short circuit current.
The Voc is called Voc because it's open circuit.
