Default Re: Working out Impediance need help!

Where to start?

What is this, a given answer or fruit of your efforts?

The top calc is correct - but only if you square (you`ve written "x2" )

The 3.142 gave it away, as in, you`d use Pi x r to the power of 2 (squared) but instead you`re using a Hz value.

Also, you`d need to substitute 230 instead of your 220 - i guessed this was Voltage (again you kept us in the dark )

The `bit` you say you`re stuck on - the `to the power of -6` part was the easy bit

x10 -6 is 1 micro units (whatever you`re working in) In other words it`s 10 /10 with 6 zero`s after it (10,000,000) The minus symbol indicates you must invert the x into divide.

Therefore in the 2nd calc, the x10 -9 will be in nano units (10 /10,000,000,000) Just basic scientific notation

Unfortunately, knowing that doesn`t really help tho` as the 2nd calc is screwed up somehow - have you an idea i wonder? Let us know if you figure out where.

Hope this helps
