1. Typical household currents are on the order of a fewamperes.
a. If a 1.54A current flows through the leads of an electricalappliance, how many electrons per second pass through it?
b. If a 1.54A current flows through the leads of an electricalappliance, how many coulombs pass through it in 5.50 min?
c. If a 1.54A current flows through the leads of an electricalappliance, how long does it take for 7.24C of charge to passthrough?
d. A copper transmission cable 170km long and a 12.5cm indiameter carries a current of 135 A. What is the potential dropacross the cable?
