Find total current in the given circuit.(General practice question)

 

You will need to apply Kirchoff's Current Law (KCL). edit: Remember that current will not flow in "broken" loop.

If that's not helpful enough, read the example here: http://physics.bu.edu/~duffy/PY106/Kirchoff.html

Extra Hint: Look up "Branch Current" or "Loop/Mesh" Methods here:

I know I have to solve it by Current divider Rule but I am stucked in calculating the total current.

 

Ignore the 7k at the upper right, as it is an open circuit.

That leaves a voltage source(12V) followed by a resistor (3k), followed by a single resistor (6k) in parallel with 3 more in series (3k, 10k, 5k).

 

I know I have to solve it by Current divider Rule but I am stucked in calculating the total current.

Well, what is your problem? Are you unable to form the equations (Loop/Mesh or Branch Methods), or able to write them down, but unable to calculate it?

 

Some people don't "See" how stuff works right away when they are just starting.

Being polite goes a long way.

 

@ Kauhu it was a problem of thevenin theorem, I had already solved it but was just confirming.

 

@ thatoneguy I was just stucked what to do with that 7k resistor, and plz don't make fun of it I just confirms my method here,thnx for ur help
