approximate I from a graph of current/time for a discharging capacitor.
no idea on this, obviously you cant see the graph, but you don't need to, id just like to know how to approximate this from a graph.
Given: i = 6 mA.
t = ?
1. Locate 6 mA on the y-axis.
2. Draw a hor. line from 6 mA to the
3. Draw a ver. line from the intersection of the hor. line and curve
to the x-axis.
4.Read the time, t , at the intersection of the ver. line and x-axis.
Note: When t is given, draw the ver. line first.
