Question

A current of 5anp. exist on a 10 ohm resistance for 4min. How much charge pass through any cross-section of the resistor this time ​

Answer 1

Answer:

5A of currents means 5 coulombs of charge is passing through the cross section in 1 second.

Thus, number of electron passing through the cross section in 1 second= 5/1.60×10^19 = 3.125×10^19 electrons are passing through that cross section in 1 second.

Answer 2

$pls \: follow \: me \: \\ or \\ give \: 5 \: thanks \\ \\ \\ \\ bts \: exo$

5A of currents means 5 coulombs of charge is passing through the cross section in 1 second, Thus, number of electron passing through the cross-section in 1 sec = 5/1.60x10^-19 = 3.125x10^19 electrons are passing through that cross section in 1 second.
