Mesh Current Analysis for Determining I1, I2, and I1 + I2 in a Network

AI Thread Summary
Mesh-current analysis is being used to calculate the currents I1, I2, and their sum in a given network. The equations for Mesh A and Mesh B have been established but the user is experiencing difficulty in simplifying them. A suggestion was made to distribute the j100 Ohm term and combine like terms to facilitate the calculation. This approach aims to clarify the relationships between the currents and voltages in the circuit. Continuing with these calculations will help in resolving the current values effectively.

Use mesh-current analysis to determine currents I1, I2 and I1 + I2 for the network shown.My calculation so far:

Mesh A: v1+v2=12∠00
Mesh B: -v2+v3=-10∠00

v1=i1RA=(47Ω)iA
v2=iAR2=R2(iA-iB)=(j100Ω)(iA-iB)
v3=iBR3=(-75j)iB

Mesh A: (47Ω)iA+(j100Ω)(iA-iB)=12∠00
Mesh B: -(j100Ω)(iA-iB)+(-75j)iB=-10∠00

I'm stuck

Have you tried distributing j100 Ohm and -j100 Ohm and then combining like terms?
 

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...
