Problem

Two long, identical copper wires A and B are connected in separate circuits. Wire A carries a steady current of

10\,\text{mA}

for

5.0\,\text{min}

. Wire B carries a steady current

I_B

for

2.0\,\text{min}

. 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. a. (i) Calculate the total charge that flows through wire A during the stated time. b. (ii) Using the condition given, find the total charge that must flow through wire B in

2.0\,\text{min}

. c. (iii) Hence, determine the value of the current

I_B

in wire B.
