Time t = 1 s

Number of Na + ions arrive at the negative electrode N = 2.68 x 10 ¹⁶

Charge of N ions q = N x 1.6 x 10 ^-19 C

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 4.288 x 10 ^-3 C

Number of Cl - ions arrive at the positive electrode N ' = 3.92 x 10 ¹⁶

Charge of N' ions q ' = N ' x (-1.6 x 10 ^-19 C )

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = -6.272x10 ^-3 C

Current in ionic solution i = ( q/t ) +(q'/t)
