Hi there

I donŽt know what level youŽre at, so I donŽt know how much I should take

for granted that you know.

Can you see the "most obvious" simplifications you make?

Like shorten out the terms in the first fraction?

When you have factors like this for exampl:

You see that the number ten is actually composed by two prime numbers, namely 2 and 5.

In the same way,

So youŽll end up with(using my example):

just forgot to mention for the second one

calculate the value of capacitence C in farads

C in farads

Indunctance L = 0.2H

Resistance R = 50 ohms

Charge Q = 15C

so if

C = L/(RQ)2

C= 0.2/(50x15)2= 0.000000355

correct?
