Answer:
Current through the wire will be 0.1024 A
Explanation:
Given that,
number of e- = 3.2×10¹⁷
time = 0.5s
charge of 1 e- = 1.6×10⁻¹⁹ C
Therefore,
Current = Charge/Time
In this case,
Charge = No: of e- × Charge of 1 e-
Charge = 3.2×10¹⁷×1.6×10⁻¹⁹ = 5.12×10⁻² C
Putting the values in the equation
Current = 5.12×10⁻²/0.5
= 10.24×10⁻² = 0.1024 A
