Using Scientific Calculators

When you are working out the time delays of monostable circuits and the output frequencies of astable circuits you will be using very small numbers.

 

Capacitance is measured in Farads, however this is a very large unit, we usually use capacitors with values of a few uF (microfarads). The easiest way is to use a scientific calculator and engineering form. Here are some examples:

1uF = 0.000001 = 1x10

 

23uF = 0.000023 = 23x10

 

230uF = 0.00023 = 230x10
