Current value I in ampere flowing in a circuit is just meant as the ratio between the applied voltage V in volt and the total resistance R in ohm the current has to overcome ...therefore :
I = V/R = 20/38 = 10/19 = 0,526 A (a bit higher than half amp)

A = V/R =20V/38 Ohm = 10/19 Amps
i = V/R = 20/38 = 0.53 ampere
