if 10 raise to 22 electrons flow through a wire in 3 seconds then what is the value of the current??
Answers
Explanation:
Q=en
Q=1.6×10^-19 × 10^22
Q=1.6 × 10^3
Q=1600C
I=Q÷t
I=1600÷3
=533.3A
Answer:
Total Current = 533.33 Ampere
Explanation :
Current is the number of electrons flowing with a charge per unit time from lower potential to the higher potential. 1 Ampere current (1A) is equal to 1 coulomb of charge (1C) per 1 second (1s) of time.
Then, it is given,
Number of electrons (n) = 10^22
Charge of each electron (e) =
= 1.6 × 10^(-19) coulombs
Time (t) = 3 seconds
We know that,
Current (I) = Charge (Q) / Time (t)
=> I = Q / t .... (1)
Also,
Charge (Q) = number of electrons (n) × charge of each electron (e)
=> Q = n•e ... (2)
From eq. (1) and eq. (2) , we get
I = (n•e) / t ... (3)
By applying the values in eq. (3), we get,
I = ( 10^22 × 1.6^(-19)) / 3
I = 533.33 Ampere
Hence, total current =
= 533.33 Ampere
