Question

Suppose H1 is the heat generated per second in the filament of a 100 W, 250 V lamp and H2 is the heat generated in the filament of a 200 W, 250 V lamp. Then H1/H2 is equal to: (a) 1 (b) 2​

Answer 1

Given,

H1 is the heat generated per second in the filament of a 100 W, 250 V lamp, H2 is the heat generated in the filament of a 200 W, 250 V lamp

To find - Ratio of H1/H2 is equal to?

H1 is 100W & H2 is 200W

So Ratio of H1/H2 is =$\frac{100}{200}$$=0.5W$
