Answer:
The charge passes a given point in the conductor during this time is 9.8 C.
Explanation:
Given that,
Current = 1.4 A
Time = 7.0 sec
We need to calculate the charge during this time
Charge :
Charge is the product of current and time.
In mathematically form,
Where, i = cirrent
t = time
Put the value into the formula
Hence, The charge passes a given point in the conductor during this time is 9.8 C.
