Electrical supplies,l as electromagnetic energy and the energy of sound (which is a form of mechanical energy). All electronic systems in order to work must have a source of energy, in particular, electrical energy. Isaac Newton, the seventeenth-century English physicist, suggested that there is a fixed amount of energ

Electrical resistance, are of equal size and at the same temperature, the amounts of electric current which flow in each piece are different. The largest current flows in the copper, less current flows in the iron, less still in the Nichrome and the current in the glass will be so small as to be virtually undetectable. T

Propagation,alternating in nature both fields will also alternate, their strengths rising and falling with time. The combination of these fields, which act at right angles to one another (as shown in figure 8.1), produce an electromagnetic disturbance or wave that is capable of energy transference from one poin

However, certain topics, particularly those listed in the chapter heading, are of particular interest to the student of electronics because they are of direct use in the process of understanding, using and servicing electronic equipme
