physics electricity simple question....

30 The current in a component is reduced uniformly from 100 mA to 20 mA over a period of 8.0 s.
What is the charge that flows during this time?
A 160mC B 320mC C 480mC D 640mC

[S.M.A.T]

current=0.5×(100+20)×8=480mC
since uniformly so the graph is like this:

There's no graph

[Vin]

There's no graph

He's on it man. Wait for it.

[S.M.A.T]

There's no graph

Vin is right i was working on it

Good job asif..........except that the current does not decrease to zero when t = 8s as shown by your graph

my graph is correct see it carefully .....i used straight line at t=8s because i don't know how to use dot-line in the paint editor

Ooh.......you should have specified :p
