... In situations where there is a variation in the current magnitude it is rather inadequate to define just the total current flow in the system. One can then use the current density as the primary parameter which is defined as the current flow per unit area. ...

... it were a wire. After a certain amount of time, the capacitor is fully charged and no current flows through it. Thus, Bulb A is brightest immediately after the switch is closed and then dims to nothing as time goes on. (f) In this same circuit, how does the brightness of B immediately when the switc ...
