Finding the current and the voltage across each resistor

AI Thread Summary
The discussion focuses on calculating the current and voltage across each resistor in a circuit with a total voltage of 24V and four resistors: R1 (270 ohms), R2 (330 ohms), and two R4 (1.2k ohms). Participants clarify that R1 and R2 are in series with the combined resistance of the two 1.2k ohm resistors, which are in parallel. The effective resistance of the parallel resistors is calculated to be 600 ohms, leading to a total resistance of 300 ohms when combined with R1 and R2. The provided current values for each resistor are confirmed, but the method to derive these values is discussed and clarified. Understanding the series and parallel relationships is crucial for solving the circuit correctly.

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 homework 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!

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
