Hello, PL Liew.

PL Liew,

Where is your work for attempting to solve this problem?

Ratch

Hi,

Ratchit:
Yes good question Ratch.

PL Liew:
Did you try this yourself yet? A quick hint is that you "kill" all sources in the circuit, then "unkill" each source one at a time and find the response to each unkilled source one at a time, then sum all those responses. When you "kill" a voltage source you short it out and disregard the resulting short circuit current, and when you "kill" a current source you open circuit it and disregard the resulting infinite voltage across it.

that's my answer. see the attached picture

Hi,

That's close, but if you use a little more precision in your calculation you'll see it comes out closer to 1.5ma, like 1.54ma, but you did get pretty close there and it looks like you did it basically right.
