Published 2013. Engineering, Environmental Science. The aim of this paper is to explain the principal mechanisms for the reduction in power demand by so called "Energy Saving Devices" (ESDs). This paper follows a similar approach as taken by Wald (1965) and Dyne (1995), where the authors use considerations of the momentum and energy equations.

The actual value of the current will depend on (1) how large the potential difference is and (2) how large the resistance (R) of the semiconductor is. An increase in the potential difference (applied. 110CHAPTER 3 DRIFT. voltage) increases the current; an increase in the resistance, however, reduces the current.
