Question

The charge flowing through a resistor $R=2\Omega$ varies with times as $Q=at-b{t}^2$, where $a$ and $b$ are positive constant.total heat

produce in $R$ is

• A. $\frac{aR}{5b}$
• B. $\frac{a^{3}R}{6b}$
• C. $\frac{a^{3}R}{6}$
• D. $\frac{aR}{6b}$

Answer 1

The correct option is B $\frac{a^{3}R}{6b}$

Hence, option $B$ is correct answer
