We often compare reluctance with resistance. In other words, production of magnetic flux lines is opposed by reluctance, and production of electric current is opposed by resistance. Therefore, we can also compare magnetic flux lines to electric current. The foregoing comparisons lead us to the idea of a magnetic circuit, as shown in Figure 1-23. This diagram shows both an electric circuit and a magnetic circuit. The electric circuit consists of the 1-volt battery and the 1-ohm coil through which 1 ampere of current 1 VOLT + 1 amp 1 TURN COIL R = 1 ohm IRON CORE WITH A RELUCTANCE OF 1 REL 1 LINE OF MAGNETIC FLUX Figure 1-23 The basic magnetic circuit.
The carbon electrodes are gradually consumed by vaporization, and an automatic mechanism is provided to maintain a fixed spacing between them. When a carbon electrode is nearly consumed, it must be replaced. All arcs generate intense ultraviolet light.

Since we must often change from Fahrenheit to Celsius temperatures, Figure 2-7 shows the relations between these thermometer scales. To change a Fahrenheit reading to Celsius, we use the following formula: C= 5 (F − 32) 9 Earth (Ground) Conduction Moist soil is a fairly good conductor, although dry soil is a poor conductor. Therefore, moist soil can be used in case of extreme necessity for part of a circuit.
