In electronics, we frequently work with very small and very large numbers. For example, the propagation delay (i.e., the time it takes for the output to change after the input has changed) for a standard digital logic gate is 0.0000000095 seconds. Moreover, the clock speed of a typical personal computer is 2400000000000 Hz. Working with numbers of this magnitude, both large and small, can be cumbersome and prone to error. For this reason we use a power-of-ten notation. With a power-of-ten notation, any number, no matter how large or small, can be expressed as a decimal number multiplied by a power-of-ten. Scientific and engineering notations are the two most common forms of power-of-ten notation. In the field of electronics, engineering notation is the preferred notation because of the direct mapping between its powers and the International System of Units (the International System of Units is abbreviated SI from the French Système International d'Unités). The SI system is the modern form of the metric system. It is the world's most widely used system of units for science and engineering.
Conclusion
1. Why is it important to use a power-of-ten notation (i.e., scientific or engineering) when expressing very large or very small numbers?
-scientific/engineering notation is important to express large numbers in a small area also it's faster to read and right
2. In engineering in general, and in electronics specifically, why do we use engineering notation rather than scientific notation?
-going by 3's allows us to label the groups instead of labeling per expo-nit
3. The SI prefix for 10-15 is femto and is abbreviated f. We do not use this prefix in electronics. Why?
-mainly because it's rarely seen

1.1.3
In the field of electronics, there are an endless number of different types of components. The ability to identify these components and to understand how they are labeled is an essential skill for anyone working in the field.
In this activity you will identify and determine the nominal values for a series of resistors and capacitors. We will concentrate on resistors and capacitors because they are part of virtually every electronics design ever made.
Conclusion
1. Why are the measured values of the resistors different from the nominal values?
-because there a tolerance and perfection is expensive
2. Identify each of the circled components for the printed circuit board shown below.
-A. Capacitor B.Capacitor C.chip D. Resistor E. LED F. Capacitor G. diode
