In the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery will be A. same in all the casesB. maximum in (i)C. maximum in (ii)D. maximum in case (iii) |
|
Answer» Correct Answer - D In case (i), R = `2Omega` Case (ii), `R = 2 + 2 = 4 Omega` Case (iii), `(1)/(R) = (1)/(2) + (1)/(2) = 1 rArr R = 1 Omega` Since, `H = (V^(2))/(R)xxt`, As voltage in the three cases for equivalent resistance is same so, `H prop (1)/(R)`. So heat produced is maximum in case (iii). |
