Expert Answer

Step 1

The quantity of electric charge that flows through the given solution or electrical wire is equal to the product of the time and current which flows through it.

Q=Ixt
Q is the charge which is passed through the given body
I is the current which is passed through the given body
t is the time taken by the charge

Step 2

The current which flows through the copper wire is given to be 0.950 A or 0.950 C/s.

Time taken by the current to flow through the wire is given to be 86 seconds.

The electric charge can be calculated as follows:

Q=Ixt
-0.950 C/sx86 s
=81.7C
