Activity 1- Problem Solving Solve the following problems involving the relationship of current, charges, and time from this equation I=Q/t. Show your complete solution. 1. If a metal wire carries a current of 80.0Ma, how long does it take for 3.00 x 1020 electrons to pass a given cross-sectional area of the wire? 2. The compressor on an air conditioner draws 40.0A when it starts up. If the start- up time is 0.50s, calculate the number of charges passing through a cross- sectional area of the circuit in this time? 3. A total charge of 9.0mC passes through a cross-sectional area of nichrome wire in 3.5s. a What is the current in the wire? b. How many electrons pass through the cross-sectional area in 10.0s? c. If the number of charges that pass through the cross-sectional area during the given interval doubles, what is the resulting current? Activity 2 - Wire or Why
