Current = q / t
q = number of electrons * charge of electron = ne
n = 10^18 electrons
e = 1.6*10^-19 coulomb
time = 12*10^-6 second
current = 10^18 * 1.6 * 10^-19 / 12*10^-6
= 0.133 * 10^5 ampere
q = number of electrons * charge of electron = ne
n = 10^18 electrons
e = 1.6*10^-19 coulomb
time = 12*10^-6 second
current = 10^18 * 1.6 * 10^-19 / 12*10^-6
= 0.133 * 10^5 ampere

Current(I)=Q/t-------------where q is the amount of charge flowing through particular circuit.
and t is time
=Time(given)=12milliseconds=12×10⁻⁶ seconds
=No.of electron or amount of charge(Q)(given)=10¹⁸
Therefore,Current(I)=10¹⁸/12×10⁻⁶=8.333A(Amperes)
and t is time
=Time(given)=12milliseconds=12×10⁻⁶ seconds
=No.of electron or amount of charge(Q)(given)=10¹⁸
Therefore,Current(I)=10¹⁸/12×10⁻⁶=8.333A(Amperes)
Charge is not given ! Number of electrons is only given !
yaa but q means charge flowing through particular circuit
again our answers are different
Q is number of electrons * charge of electron
Yes :/
let see wat happens
Ok
