Help with Physics HW
If a current of 2A flows through a lamp filament, find the number of coulombs that flow through the filament each minutes?
Can anyone help me with question and explain it
An ampere is one coulomb of charge going past a given point in the duration of one second.
I = Q/t
Q = It
where Q is your coulomb of charge, I is your current and t is time in seconds.
Since we have 2 Amperes, thats 2 coulombs of charge going through your lamp filament per second. The question asks for coulombs per minute so you just convert 2coulombs/sec to number of coulombs/1minute:
(2coulombs/1sec) * (60sec/1minute) = 120 coulombs per minute
ok i got it..
Thx a lot.
