How much energy is stored in the electrical fields in the capacitors (in total) shown below? (b) Is this energy equal to the work done by the 400−V source in charging the capacitors? The current through a 12-gauge wire is given as I(t) = (15.00 A)∗sin⁡[2π(120 Hz)t]. What is the current density at time 10.00 ms ?
