Thanks. I took your advice but I still cannot get the correct answer. I calculated 6.7 volts being dissipated across the resistor and concluded that the inductor would have to be less than 3.3volts. This answer choice was wrong however. The answer choices are 6.7V, 2.5V, 3.4V, 10V, and 7.6V. 10V...
Homework Statement
An oscillator producing 10 volts (rms) at 200 rad/s is connected in series with a 50 Ω resistor, a 400 mH inductor, and a 200 μF capacitor. The rms voltage (in volts) across the inductor is

The Attempt at a Solution
I feel that since water waves are in fact waves, they can no doubt interfere with...

Do magnetic fields occupy space?
Homework Equations
The Attempt at a Solution
I think the answer is no but I am having a terribly difficult time explaining why. All I have seen online is that like light, the magnetic field is composed of non-massive particles...
Sorry about that.
Q=CV, C=(epsilon)A/d, V=Ed/ By substituting these last 2 equations into the first, the result is Q=(epsilon)A(E)-->8.85e-12(0.2)(2e6)= 3.54e-6. However, this is half of the correct answer. What am I doing wrong?
Homework Statement
A parallel-plate capacitor has a plate area of 0.2 m2 and a plate separation of 0.1 mm. To obtain an electric field of 2.0 × 10^6 V/m between the plates, the magnitude of the charge on each plate should be

Homework Equations
V=IR, Kirchoff's Law
The Attempt at a Solution
The voltage drop across resistors in parallel are equivalent due to Kirchoffs law (at least I think so?), so V=R(eq,top)I(top)=R(eq,bottom)I(bottom)-->...

Homework Equations
V=IR, Kirchoff's Law
The Attempt at a Solution
I thought that since the resistors are in parallel, the voltage drop across each one would be equivalent, so V=I1(14)=I2(38)=I3(7)=I4(Rx). From here I became stuck. Please help!
