    Hard Transformer
Click For Summary
The discussion revolves around calculating transformer parameters, specifically the secondary current and primary current. The user initially calculated the secondary current as 12A but expected 24A, seeking clarification on the correct approach. It is noted that for an ideal transformer, the power input equals the output power, which is crucial for solving the problem. The user also inquires about the secondary voltage and the power across a resistor connected to the transformer’s output. The conversation emphasizes the importance of understanding transformer equations and relationships between voltage and current.

Homework Statement

The Attempt at a Solution


for part a): I tried to use the equation N2/N1= I1/I2
I got 12A, instead of the answer (24A)

can someone please show me how to do this? I missed class one day, and now I'm lost

help..anyone??
 
How much is the secondary voltage?

A resistor is connected across the secondary terminals. How much current flows through the resistor?

This current is the secondary current of the transformer. How much is the primary current?

If it is not stated otherwise, you can take the transformer ideal. It means that the power input is equal to the output power.

You know both the voltage and current across the resistor, connected to the output of the transformer. How much is the power on the resistor?

Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
