A capacitor has been charged to a constant potential V. At this moment in time, the displacement current between its plates: is zero is equal to the current that was required to charge up the capacitor O is equal to the voltage is nonzero and constant

What Hall voltage is produced by a 0.200T field applied across a 2.60-cm-diameter aorta when blood velocity is 60.0 cm/s?

A particle of charge +q and mass m moves with velocity v0 pointed In the +y-direction as It crosses the x-axis at x= R at a particular time. There is a negative charge -Q fixed at the origin, and there exists a uniform magnetic field B0 pointed in the +z-direction. It is found that the particle describes a circle of radius R about -Q. Find B0 in terms of the given quantities.

Assume that V is a function of x and at x =2, V =20 volt and at x = 4, V = 30 volt. a) Find V, E, Ej and draw these with respect to x-axis. 30uc b) Now if p, and e, = 3. Find V. E. E and draw these with respect to x-axis.

At position x=0 the voltage is 100V. At x=0.5m the voltage is 0V. What is the direction and strength of the average x-component of the electric field in that region?

A parallel-plate capacitor with plate separation d is connected to a source of emf that places a time-dependent voltage V(t) across its circular plates of radius r0 and area A = πr0 2 (see below). (a) Write an expression for the time rate of change ofenergy inside the capacitor in terms of V(t) and dV(t)/dt.(b) Assuming that V(t) is increasing with time, identify thedirections of the electric field lines inside the capacitor andof the magnetic field lines at the edge of the region betweenthe plates, and then the direction of the Poynting vectorS →at this location.(c) Obtain expressions for the time dependence of E(t), forB(t) from the displacement current, and for the magnitudeof the Poynting vector at the edge of the region between theplates.(d) From S → , obtain an expression in terms of V(t) anddV(t)/dt for the rate at which electromagnetic field energyenters the region between the plates.(e) Compare the results of parts (a) and (d) and explain therelationship between them.

If you work out enough to visibly increase the diameter of your biceps, will this increase or decrease your susceptibility to electric shock? Explain.

Why can't the current flow uniformly (linear over time) when the capacitor is charging or discharging? For example, why doesn't the charge just flow at a steady rate off of the capacitor while discharging?
