Determine ( I L ) in the following circuit (the current "above" the 3 kΩ resistor).
Voltage division law
V (for series resistor) = (V in) * [ (resistor)(total series resistance) ]
Kirchoff's rules: I in = I out
Total potential difference in a loop = 0
The Attempt at a Solution
Okay, a lot of this is still new to me, so forgive me if I miss something.
(The "I L" should also be "I l," as it is just a listed current )
But, there's no potential difference given so how are you able to find the current asked? Would you say voltage is equal for everything in the circuit?
I try to sum all current out from left to right on the bottom as:
I tot = I l + 4(I x) - 3mA but still unknowns everywhere when all I want is I l.
Where should I start?
