Experiment 2 - The Resistor II
Just by how much the current is regulated by a resistor
is represented by the unit ohm.
For a fixed voltage,
the resistance limits the current to a maximum value.
Therefore, the more ohms a resistance has,
the less current it lets through.
Replace in your circuit the resistor R1
by a resistor of 4,7 kΩ.
If you press the pushbutton switch now,
the LED lights up only slightly.
Repeat the experiment with a
47 kΩ resistor
and the LED stays dark.
What happens to the current flowing through a resistor?
You take a good look at it in the next experiment.
