Question

a 2v cell is connected to 1ohm resistor .How many electron come out the terminal of cell in 2 min?​

Answer 1

Answer:

Explanation:I= V/R  [By Ohm's Law]

                    I= 2/1 =2A

                    I= Q/t

Therefore, t= 2min

Q=I*t

  =2*2=4

Q= ne

4= n* 1.6 * 10^-19

n= 4/1.6*10^-19

  = 2.5*10^19
