Expert Answer:
Dear Student
Power (wattage) P= i2R = V2/R ===> R= V2/P -----(1)
R1=202/100 =4 ohm
R2= 2202/25 = 1936 ohm
Effective resestance of teh circuit R= R1R2/(R1+R2) -----(2)
R=7744/1940 = 3.992 ohm
Total current I= I1+I2 = V/R= 220/3.992 =55.11 A
I1= V/R1= 220/4 =55 A
I2= V/R2=220/1936= 0.11
