Question

7. Calculate the number of electrons passing a point in the wire in 1 min when the current is 1A

Answer 1

Answer:

Current Electricity

Explanation:

★ Current ( I ) = charge ( q ) / time ( t )

[ Charge ( q ) = no. of electrons ( n ) × charge of electron ( e ) ]

» I = n × e / t

1 = n × e / 60 seconds

n × e = 60

n = 60 / e = 60 / 1.6 × 10-¹⁹

★ No. of electrons ( n ) = 375 × 10¹⁸ electrons . ★
