What is the ratio of heat generated in R and 2R

Two wires having resistance R and 2 R are connected in parallel, the ratio of heat generated in 2 R and R is

Two wires with resistances R and 2 R are connected in parallel, the ratio of heat generated in 2 R and R is

If two wires having resistance R and 2 R . Both joined in series and in parallel then ratio of heat generated in this situation, applying the same voltage,

When two resistances R_1 and R_2 are connected in series , they consume 12 W powers . When they are connected in parallel , they consume 50 W powers . What is the ratio of the powers of R_1 and R_2 ?

When two resistances R_1 and R_2 are connected in series , they consume 12 W powers . When they are connected in parallel , they consume 50 W powers . What is the ratio of the powers of R_1 and R_2 ?

Two resistors R and 3 R are connected in series. Ratio of rate of heat dessipated in R to that in 3 R is x_(1) . Similarly when R and 3 R are connected in parallel to each other, ratio of the heat dessipated in R to that in 3 R is x_(2) . What will be the value of x_(2)//x_(1) ?
