17. In electronics there is a need for defined units of measurement to describe a circuit and its properties. There is also a need to represent very large numbers and very small numbers with accuracy and with ease, usually within the same circuit or problem.

18. Engineering Notation All powers of 10 must be 0 or multiples of 3. The mantissa must be greater than or equal to 1 but less than a 1000. (1 – 999) mantissa The number left of the decimal.

28. Chapter 1 page 5 Benjamin Franklin speculation of the wool rubbing something off of the wax, the type of charge that was associated with rubbed wax became known as ”negative” (because it was supposed to have a deficiency) while the type of charge associated with the rubbing wool became known as ”positive” (because it was supposed to have an excess).

31. Charge

32. Volt One coulomb of charge is the total charge associated with 6.242 x 10 18 electrons. If a total of 1 joule (W) of energy is used to move the negative charge of 1 coulomb (Q), there is a difference of 1 volt (V) between the two points. V=W/Q we will use “V or E”

33. Voltage Potential: existing in possibility ; capable of development into actuality. Applied voltage is the starting mechanism.

35. Chapter 1 page 8 The electrons of different types of atoms have different degrees of freedom to move around. This relative mobility of electrons within a material is known as electric conductivity. Conductors versus Insulators.

36. Chapter 1 page 8-9 Insulators: glass rubber oil fiberglass quartz (dry) cotton (dry) paper plastic air pure water

37. Copper is the most commonly used metal in the electrical/electronics industry. It has 29 electrons in orbits around the nucleus, with the 29th electron appearing all by itself in the 4 th shell.

39. Chapter 1 page 9 Uniform motion of electrons is what we call electricity, or electric current.

41. Current Applied voltage is the starting mechanism. V or E Current is a reaction to the applied voltage. A or I

42. Current You can have voltage and or resistance without current. You must have voltage to create current and you need a resistance to that current.

43. Chapter 1 page 10 Concept there must be a complete path for current.

44. Page 10 - 11 A thin, solid line is the conventional symbol for a continuous piece of wire. However, the flow will be interrupted if the conductive path formed by the wire is broken:

50. Page 23 This circuit is not a practical one. The reason is that it is dangerous because the magnitude of current may be very large This is a short circuit, and the release of energy can be dramatic. What is missing?

52. Page 23 It can be said that conductors have low resistance and insulators have very high resistance. This resistance serves to limit the amount of current through the circuit.

53. The symbol for a resistor. Resistance is measured in Ohms. R or Ω

55. Page 27 A short circuit is an electric circuit offering little or no resistance to the flow of electrons. An open circuit is one where the continuity has been broken by an interruption in the path for electrons to flow. A closed circuit is one that is complete, with good continuity throughout.

56. Resistance Ohms Opposition to the flow of charge through an electrical circuit, called resistance, has the units of ohms and uses the Greek letter omega (Ω) as its symbol.
