Formula: I = Q/t
where
I = Current in Amps
Q = charge in coulombs
t = time in seconds
Solved Examples & Calculations
Example#1: Certain area has 1000 coulombs of charge passing in a time interval of 30 seconds. Find the electric current.
Solution:
I = Q/t = 1000 C/30 s = 33.33 A
Example#2: Compute current in mA for same example.
I = Q/t = 1000 C/30 s = 33.33*1000 mA = 33,3330 mA
Example#3: Certain imaginery plane has 2500 coulombs of charge passing for 3 minutes. Find the electric current.
Solution:
I = Q/t = 2500 C / (3*60s) = 13.88 A
