Question
find the total momentum of electrons in a straight wire of lenght 1000m carrying a current of 70A.
Answers
drwls
electron momentum in length L of wire =
I*(m/e)*L
where I is the current flowing, m is the electron mass and e is the electron charge.
= 70 C/s*9.81*10^-^31 kg*1000 m
/1.6*10^-19C
= 4.3*10^-7 kg m/s
I*(m/e)*L
where I is the current flowing, m is the electron mass and e is the electron charge.
= 70 C/s*9.81*10^-^31 kg*1000 m
/1.6*10^-19C
= 4.3*10^-7 kg m/s
