Current Q = It

Question 1 What charge is moved if a current of 0.5 Amps flows for 10 seconds? Q = It Q = 0.5A x 10s Q = 5C

Question 2 What charge is moved if a current of 0.30 Amps flows for 10 minutes? Q = It Q = 0.30A x (10 x 60)s Q = 180C

Question 3 What is the current if 100 coulombs flows in 10 seconds? I = Q/t I = 100C / 10s I = 10 A

Question 4 What is the current if 100 millicoulombs flows in 5 seconds? I = Q/t I = (100/1000)C / 5s I = 0.1C / 5s I = 0.02 A

Question 5 How long does it take 100 coulombs to move at a rate of 4 amperes? t = Q/I t = 100C / 4A t = 25s

Question 6 How long (in seconds and then hours) does it take 50 Megacoulombs to move at a rate of 5 amperes? t = Q/I t = 50x106C / 5A t = 10 000 000s t = 10 000 000/(60 x 60) = 2778h
