Calculating Currents & Voltages of an RLC Circuit

Click For Summary
In an RLC circuit with a 15Ω resistor, 200μF capacitor, and 12mH inductor, the current through each component is 1.75A⋅cos(250πt). The voltage across the power source is calculated to be 26.79V⋅cos(250πt+0.201). The voltage across the resistor is 26.25V⋅cos(250πt), while the capacitor has a voltage of 11.14V⋅cos(250πt-(π/2)). The inductor's voltage is 16.49V⋅cos(250πt+(π/2)). The calculations confirm the expected relationships between current and voltage in the circuit.

Homework Statement


An RLC circuit contains the following components in series: a 15Ω resistor, a 200μF capacitor, and a 12mH inductor. What are the currents and voltages through each component?

It's known that the current through the resistor is 1.75A⋅cos(250πt)

Homework Equations


χL=ω*L
χC=1/(ωC)
Z=√(R2+(χLC)2)
φ=tan-1((χLC)/R)
Vi=Ii*Z

The Attempt at a Solution


This what I got when solving:

The current through each component is the same. I=1.75A⋅cos(250πt)

The voltage across the power source is V=26.79V⋅cos(250πt+0.201)

The voltage across the resistor is V=26.25V⋅cos(250πt)

The voltage across the capacitor is V=11.14⋅cos(250πt-(π/2))

The voltage across the inductor is V=16.49⋅cos(250πt+(π/2))

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)...
