what must be resistance value in the load side so that it matches reference value of $6\mathrm{.}664$A or provide suitable reference value for $12$v output voltage so that we can transfer load to slave transformer if load is increasing greater than set value and shut down transformer if load is beyond capacity of both transformer.. also provide code for this "automatic load sharing of transformer using arduino UNO" $..$ Specification of tranformer is $230$v$-12$v AC $..$ according to figure provided, give code for this project..
