Problem
Two long, identical copper wires A and B are connected in separate circuits. Wire A carries a steady current of 10mA for 5.0min. Wire B carries a steady current IB for 2.0min. The total number of electrons transported through wire B in its time interval is exactly the same as that through wire A in its interval.
(i) Calculate the total charge that flows through wire A during the stated time.
(ii) Using the condition given, find the total charge that must flow through wire B in 2.0min.
(iii) Hence, determine the value of the current IB in wire B.
