An electric device delivers a current of 5.0 A for 10 seconds then the number of electrons flowing through this device would be 3.125ₓ10²⁰
<h3>What is an electric charge?</h3>
Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge (commonly carried by protons and electrons respectively). Unlike charges attract one another while like charges repel one another. We refer to an object as neutral if it has no net charge.
Electric current is defined as the charge per unit of time.
The mathematical relation between current and the electric charge
I =Q/T
where I is the current flowing
Q is the total electric charge
T is the time period for which the current is flowing
By using the above relation between electric current and electric charge
I =Q/T
By substituting the values of current and time
5 =Q/10
Q= 50 Coulomb
The charge on one electron is -1.6 ×10⁻¹⁹ coulomb.
The number of electrons = Total charge /charge on the one electron
=50/1.6×10⁻¹⁹
=3.125ₓ10²⁰
Thus, the total number of electrons flowing through the device would be 3.125ₓ10²⁰.
