Physics Project: LDR Current Study

This document is a student's dissertation report on studying the variation of current using a light dependent resistor (LDR). It was submitted to fulfill partial requirements for a C.B.S.E practical examination under the guidance of Ms. Manisha. The student, Himesh Jain, certified that the work presented is authentic and of their own work. Ms. Manisha also certified that the project entitled "To Study The Variation Of Current Using a LDR" was bonafide work carried out by Himesh Jain under her supervision. The report includes sections on half wave and full wave rectifiers, components of rectifiers, characteristics of half wave and full wave rectifiers, and conclusions.
