An electric dryer connected to a 120-V source draws 8.0 A of current. For the electric dryer, find the number of coulombs that flow through in 0.70 min.

Answer 1

q = it

i = 8.0 A = 8.0 coulombs/s

t = 0.70 min = 0.70(60 s) = ? seconds

Plug in the current in A and the time in seconds, and get q in coulombs.
