General Electronics questions! homework is awesome if you know what your doing!

[JOEMARSH]

SO I am about 6 classes into my Intro to Electronics at College...Im glad to be joining the ranks of other EE's!

BUT I need some help..Having trouble understanding some basic principles

I'm using SI unit prefixes

Prefix Symbol Value
tera T 10 to the 12 power
giga G 10 to the 9th power
mega M 10 to the 6th power
kilo k 10 to the 3rd
- 10 to the 0power
milli m 10 to the -3
micro u 10 to the -6
nano n 10 to the -9
pico p 10 to the -12
femto f 10 to the -15

What Im having trouble with in the problem is...

Express with the most appropriate prefix:
a-12,000 s
b-340,000,000 s
c-0.00050 s
d-0.00000007 s

The only reason Im having trouble is, I cant seem to figure out, where they want me to convert it to? they want me to change it? Im lost if any one can help me!!

Thanks in advance...JOE

So my 12,000 s is my unity multiplier? Basically where I am starting the equation out at?

Then if I am making it bigger, I multiply

AND if I am making it smaller, then I Divide

IS this right guys?

I'm also building my own La-2a right now as a electronics project...all old analog technology...point to point wiring and everything...

Simple use unit converter!!!!.

Express with the most appropriate prefix:
a-12,000 s ----- can be expressed as 1.2E+10 micro
b-340,000,000 s -----can be expressed as 340 yota or simply 3.4E+11 milli
c-0.00050 s -----can be expressed as 5E-10 mega
d-0.00000007 s -----can be expressed as 7E-11 kilo

Though there are other ways to express. I think this how you wanted.

Thankyou

I would say it should be:

a - 12K
b - 340M
c - 500u or 0.5m
d - 70n

Absolutely. 'Engineering Notation' generally expresses everything as a number between 1 and 999 followed by a multiplier.
