Book excerpt: Excerpt from Practical Electricity: Laboratory and Lecture Course, for First Year Students of Electrical Engineering One of the great difficulties experienced by people in mastering the quantitative science of electricity, arises from the fact that we do not number an electrical sense among our other senses, and hence we have no intuitive perception of electrical phenomena. During childhood we did not have years of unconscious experimenting with electrical forces as we had with the forces connected with the sensations of heaviness and lightness, loudness and softness, heat and cold. Beyond a shock or two taken perhaps from some medical galvanic apparatus, or from a Leyden jar, our senses have never been affected by electrical action, and hence we ought to begin the study of electricity as a child begins its early education. Quite an infant has distinct ideas about hot and cold, although it may not be 'able to put its ideas into words, and yet many a student of electricity of mature years has but the haziest notions of the exact meaning of high and low potential, the electrical analogues of hot and cold. That it is desirable that students should learn physics, as they learn to ride the bicycle, by experiment ing themselves, is now generally admitted, and this is especially true in the case of electricity, since it is by experimenting, and only by experimenting, that a student can obtain such a real grasp of electricity that its laws become, so to say, a part of his nature. Hence, in the courses of electricity which I arranged at the City and Guilds of London Technical College, Finsbury, and at their Central Institution, for every hour that a student spends at lecture, he spends several in the laboratory.
