Engineering Notation and Prefixes

The video tutorial explains engineering notation, a system used in electronics to handle very large and small numbers. It covers the differences between engineering and scientific notation, focusing on the base number and exponent multiples. The tutorial details prefixes for small numbers (milli, micro, nano, pico, femto) and large numbers (kilo, mega, giga, tera, peta). Practical examples demonstrate converting voltages and currents into engineering notation. The video also provides tips on using calculators to handle these notations effectively.

Why is engineering notation important in electronics?

• It simplifies the representation of very large and small numbers.

• It is a method to calculate power consumption.

• It helps in designing electronic circuits.

• It is used to convert units of measurement.
