THE PRACTICAL KNOWLEDGE OF THE STUDENTS IS VERY ESSENTIAL AS THEORY AND EXPERIMENTS IN ENGINEERING AND TECHNOLOGY GO HAND IN HAND. THE BOOK IS WRITTEN IN A SIMPLE AND LUCID LANGUAGE WITH A GREAT EMPHASIS ON THE EXPERIMENTAL RATHER THAN THE THEORETICAL ASPECT TO EACH EXPERIMENT. OF COURSE, THE THEORY AND THE PRINCIPLE OF EACH EXPERIMENT NECESSARY FOR ITS SUCCESSFUL PERFORMANCE HAS BEEN DULY DESCRIBED AND DISCUSSED. A BRIEF DESCRIPTION OF THE ASSEMBLAGE OF THE ACTUAL APPARATUS ALONG WITH THEIR ACCESSORIES HAS BEEN GIVEN WITH SELF EXPLANATORY OBSERVATION TABLE WHICH ALSO ILLUSTRATE THE SEQUENCE OF METHOD AND OTHER IN WHICH STUDENT HAS TO RECORD THEIR OBSERVATIONS IN A PROPER SCIENTIFIC MANNER. THE VARIOUS PRECAUTIONS WHICH ARE TO BE FOLLOWED BY THE STUDENTS DURING THE PERFOEMANCE OF EXPERIMENT ARE GIVEN IN SIMPLE LANGUAGE. A SPECIAL FEATURE OF THE BOOK IS THAT AT THE END OF EACH EXPERIMENT A SERIES OF QUESTIONS WITH THEIR ANSWERS BASED ON INSTRUMENTATION AND THEORETICAL ASPECT FOR PROPER UNDERSTANDING OF THE EXPERIMENT ARE GIVEN
