Homework Statement

Q . Find current i through the 5Ω resistor ?

Homework Equations

The Attempt at a Solution

I would like to understand what does leftmost 1A represent . I haven't seen something like that before in my book . Is it a Galvanometer or something else ?

It is a current source.

 

[Jahnavi]

It is a current source.

OK .

I am getting option d) i = 0 . Is that correct ?

 

[gneill]

OK .

I am getting option d) i = 0 . Is that correct ?

You'll have to show the details of your work. We won't just confirm or deny what could potentially be a guess

That is correct.

Btw, you can check it yourself using node voltage method and KCL.

you can check it yourself using node voltage method and KCL.

I did use KCL and KVL to arrive at the result .Using the current source and KCL , I assigned current in all the resistors . Then I wrote 2 KVL eqns. for the upper and bottom right loop .

Thanks a lot

Well done!
I myself prefer the node voltage method to avoid any silly mistakes while writing KVL.
