Finding Turns Ratio for Different Transformer Configurations

AI Thread Summary
The discussion focuses on calculating the turns ratio for different transformer configurations using impedance values provided. The transformer is designed to match various impedances, specifically 600 W to 10 kW and 150 W to 10 kW. The user seeks clarification on applying the formula Rl/Rp=(Ns/Np)^2 for the given configurations and whether to consider each impedance pair separately. Participants emphasize that while they can offer hints, they will not complete the calculations for the user. Understanding the relationships between the impedance values and the turns ratio is crucial for solving the problem.

So I was studying on transformer calculations and understand it all pretty well until coming across these questions that I don't really understand. There's about 6 of them but if someone could work out 2 for me so I can understand it and finish it off it would be much appreciated.
Thanks

Electrical Specifications: Impedance at 1 kHz
1 - 2 150 W

2 - 3 150 W

1 - 3 600 W

4 - 5 10 kW

DC Resistance

1 - 3 23 W

4 - 5 400 W

Rated Power 2 W

-->This transformer is designed to match impedances 600 W (pins 1-3) to 10 kW (pins 4-5) or 150 W (pins 1-2 or 2-3) to 10 kW (pins 4-5).

-->Note that you can reverse primary and secondary to match 10 kW (pins 4-5) to either 150 W (pins 1-2 or 2-3) or 600 W (pins 1-3).

For each of the configurations in Figure 11, calculate the turns ratio NS/NP. Use Equation (6) and the transformer specifications on page 6 to calculate the turns ratios for each combination and provide a formula that gives VS as a function of VP. Enter your results in the table below.

NS/NP:

VS = f(VP):

Step-up / Step-down:

My attempt:
so I'm trying to figure out the turns ratio of each of them and I think you use the formula Rl/Rp=(Ns/Np)^2 where n is the amount of turns and R is the impedance. would the impedance be 600 ohms and 10 k ohms? do I have to consider each part as 1-2, 1-3 and 4-5?

Sorry, but PF is not a homework service.

If you want to take a stab at solving your problem, we'll provide hints and suggestions, but we don't do your work for you. It's against the Rules.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
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 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
