Black Box with a potentiometer
The 10-turn potentiometer is inside the black box featuring two outputs. We measure the resistance as a function of the handle angle of rotation and determine the wiring diagram.
Black Box
Set of 4 electricity experiments
A set of four experiments with increasing difficulty, in which we should measure and interpret I-V curves. https://www.youtube.com/watch?v=mAWgILhu7EEhttps://www.youtube.com/watch?v=l9tY7N5Id14
A triangle Black Box
In this experimental problem, we determine the wiring diagram of the black box by charging a capacitor inside and discharging it through a voltmeter.
Star Black Box
In this problem, we determine the parameters of resistors and capacitors connected in a star diagram inside a black box with four outputs.
Black Box with a switch and a potentiometer
In this problem, we determine the parameters of elements in a bridge circuit with a button and a potentiometer.
