How to get the answer to a formula if I=ã2P/L relates the coefficient of selfinduction, L (in henry's), the energy P stored in an electronic circuit (in joules), and the current I (in amps). Find I if P=120 and L=70.
The example I have to go by does not help with rounding to the nearest thousandth. Find I if P=90 and L=70
Formula I=ã2P/L
=ã2*(90)/70
=ã180/70
= 1.604 amps

rounding to the nearest thousandth? I find it difficult this is an issue in college.
Consider the number...
ab.cdefghij
a is the tens digit
b is the units digit
c is the tenths digit
d is the hundreths digit
e if the thousandths digit
f is the ten thousands digit
take a look at f. Is if 5 or greater? if so, increase the thousandths by one, then drop f,g,h and so on.
