1.	A Resis†an ce R is connected in parallel with a variable resis†an ce r . Then they are connected in series with resis†an ce R . They are joined to a battery of V voltage . Resis†an ce r is variable resis†an ce . If for r = fR , the heat generation in r is maximum , then the value of f is (1) 1/2 (2) 1 (3) 1/4 (4) 3/4
