Current Resistor

AI Thread Summary

To calculate the current through a resistor, Ohm's Law (V = I * R) is used, allowing for the rearrangement to I = V/R. For power absorbed by a resistor, the formula P = VI is applied, where V is the voltage across the resistor and I is the current through it. To find the equivalent resistance seen by a source, one must analyze the circuit configuration, which may involve series and parallel combinations. The discussion highlights the importance of understanding these fundamental electrical concepts. Overall, the thread emphasizes basic calculations related to resistors in electrical circuits.

Do I use Ohms Law V = i * R?

wayneo

use I = V/R then for power, P = VI

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...
