    Time-Varying Electric Field in Parallel Plate Capacitor

    Ok, so let's say that the plates have an extremely large area, and the distance between them is small. Then you're saying that E(t) = V(t)/d (where E points from the positive plate to the negative plate) is a very good approximation to the E field near the centre of the plates, far removed from...

    Time-Varying Electric Field in Parallel Plate Capacitor

    Ok, so if I understand this correctly: If a parallel plate capacitor is subjected to a sinusoidal voltage, then the E field between the plates is not actually given by E(t) = V(t)/d, contrary to what my textbook (Fundamentals of Applied Electromagnetics, page 299) states? My textbook uses E(t)...

    Time-Varying Electric Field in Parallel Plate Capacitor

    Hi, A time-varying (sinusoidal) voltage source is applied to a parallel plate capacitor of length d. Then the E field will vary according to E(t) = V(t)/d. However, this suggests that, for any given time, the E field is constant with respect to spatial coordinates. Therefore, the curl of E is...

    Does Taking a Step Forward Affect Age Difference in Time Dilation?

    I just started learning about relativity and time dilation last night. It's extremely interesting, and I have a quick question. Suppose two people (Steve and John) and standing side by side. Steve is *exactly* 1 year older than John. If either one of them takes a step forward, and the other...
