This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying the p–n junction diode theory. Since the current flows in only one direction in the diode, we can turn on the LED in four different ways in the electrostatic induction process using a rod charged with (+) or (−). In each case, having students predict the transfer of charges and having the opportunity to interpret the measurement results will help us get a clearer understanding of how the charges move through the LED during the electrostatic induction process.
