Homework Statement


Find the current and the voltage across each resistor.

volts is 24v
R1=270 ohms
R2=330 ohms
R2=1.2k ohms
R4=1.2k ohms


Homework Equations





The Attempt at a Solution


This is not a hw its more like a study guide.
He gave us the answer for just the currents which are
IR1=20
IR2=20
IR3=10
IR4=10
But not sure how he got that.
this is what i did but don't know how to go from there:
(270+330)|| (1.2k||1.2k)
600||600
R=300

Hi Lopez. Welcome to physics forums!!!

The 270 and 330 are in series with the 600, not parallel.

Having reduced the (1.2k||1.2k) to an effective 0.6k, what is the relationship of that in the circuit to R1 and R2?

ahh yes there was the problem,after 1.2 k and the other 1.2k were combined it becomes one resistor in series with the (r1 and R2). Thanks!
