Calculation of Electric Charge
The electric charge flowing through a circuit can be calculated using the formula:
Electric charge (Q) = Current (I) x Time (t)
Given that the current (I) is 0.25A and the time (t) is 10 minutes, we can substitute these values into the formula:
Electric charge (Q) = 0.25A x 10 minutes
Electric charge (Q) = 2.5 Coulombs
Therefore, the amount of electric charge that flows through the circuit is 2.5 Coulombs.
Calculation of Total Number of Charges
To find the total number of charges flowing through the conductor during this time, we can use the fact that 1 Coulomb is equal to 6.24 x 10^18 charges.
Therefore, the total number of charges can be calculated by dividing the electric charge (Q) by the elementary charge (e):
Total number of charges = Electric charge (Q) / Elementary charge (e)
Given that the electric charge (Q) is 2.5 Coulombs and the elementary charge (e) is 6.24 x 10^18 charges, we can substitute these values into the formula:
Total number of charges = 2.5 Coulombs / (6.24 x 10^18 charges)
Total number of charges = 4.006 x 10^18 charges
Therefore, the total number of charges flowing through the conductor during this time is approximately 4.006 x 10^18 charges.
Explanation
- The electric charge flowing through a circuit is calculated by multiplying the current (I) by the time (t).
- In this case, the current is given as 0.25A and the time is given as 10 minutes.
- By substituting these values into the formula, we find that the electric charge flowing through the circuit is 2.5 Coulombs.
- To find the total number of charges, we divide the electric charge by the elementary charge, which is the charge of a single electron.
- The elementary charge is approximately 6.24 x 10^18 charges per Coulomb.
- By dividing the electric charge of 2.5 Coulombs by the elementary charge, we find that the total number of charges is approximately 4.006 x 10^18 charges.
- This means that during the 10 minutes of operation, approximately 4.006 x 10^18 individual charges flowed through the conductor.
- It is important to note that the total number of charges is not the same as the amount of electric charge, as the total number refers to the individual charges while the electric charge refers to the sum of their magnitudes.
