In 10 s, 10 ^ 20 electrons passed through the cross section of the conductor. What readings does the ammeter give?
| May 9, 2021 | education
These tasks: t (time of passage of electrons through the cross-section of the conductor) = 10 s; N (number of electrons) = 10 ^ 20 electrons.
Constants: e (value of the electron charge) = 1.6 * 10 ^ -19 Cl.
1) The charge passed through the cross-section of the conductor: q = N * e = 10 ^ 20 * 1.6 * 10 ^ -19 = 16 C.
2) Ammeter readings: I = q / t = 16/10 = 1.6 A.
Answer: The current shown by the ammeter is 1.6 A.
