How to get frequency, w (omega), when calculating reactance

AI Thread Summary
The discussion revolves around calculating inductive and capacitive reactance using the formulas XL = jwL and XC = 1 / jwC. A discrepancy arises regarding the frequency value, where the professor states omega (w) as 10000, but the question indicates a frequency of 6 cos(10^3t), suggesting omega should be 1000. Participants agree that this likely indicates a typo in the solution sheet. Clarification on standard frequency values is sought, but the focus remains on resolving the inconsistency in the provided frequency. The conversation highlights the importance of accurately identifying frequency in reactance calculations.

Hi,
I came across a question from our weekly set of questions that involved finding the inductive reactance and capacitive reactance, ie: XL = jwL and XC = 1 / jwC.
In the solution sheet, the professor wrote that the frequency, w (omega) = 10000, however, in the question sheet, it was nowhere to be found. Is 10000 the standard frequency or is there a way of determining it?
I will upload 2 images of the solution to illustrate my query:

The frequency is specified as is = 6 cos(10^3t) in the form Acos(wt). So I think it might be a typo. I think omega should be 1000, not 10000.
 
@analogdesign , Oh yeah, of course. My bad. Thanks
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
