3.For a given resistance X in the figure shown the thermal power generated in'Y is maximum whenY 40. Then resistance X (in ) is:10V,20T60A series parallel combination af hatteres e

Answer»

Theremal power generated in Y will be maximum when maximum current flows through the circuit i.e for least resistance now 2+4 =6 ohm is fixed now so the value of the unknown resistance should be 6 ohm

wrong
