NEET 2016 Physics Heating Effect of Current MCQ Question
Type: MCQ-numerical-Hard-Class 12
The charge flowing through a resistance R varies with time t as Q = at − bt², where a and b are positive constants. The total heat produced in R is
A
a³R/2b
B
a³R/3b
C
a²R/6b
D
a³R/3b
Correct Answer
Option C
Detailed Explanation
The heat produced is given by integrating I²R over time. Substituting the expression for current and integrating gives the total heat as a³R/2b.
