Heat is produced at a rate given by H in a resistor when it is connected across a supply of voltage V. If now the resistance of the resistor is doubled and the supply voltage is made V//3 then the production of heat in the resistor will be |

Answer» Solution :`H=(V^(2))/(R )""…(i)` When R is doubled and V becomes `(V)/(3)`, then `H.=((V//3)^(2))/(2R)=(1)/(18)(V^(2))/(R)=(H)/(18)` (USING (i)) |
