Equations How to visualize the current Current measures the flow of charges through an area over time. Figure 1 shows a wire with charges q moving to the left through the wire, which has a cross sectional area A . Imagine we counted how many charges passed through the cross sectional area in one second. This rate is the current. Figure 1.
The current density varies with radial distance r as J=a r^2, in a cylindrical wire of radius R. The current passing through the wire between radial distance R/3 and R/2 isdisplaystylefrac25pi aR^472displaystylefrac{81pi
Step 1/2 First, we need to find the total current in the wire for both cases (a) and (b). To do this, we’ll integrate the current density over the cross-sectional area of the wire.
