# The energy dissipiated by a resistor is 10 mJ in 1s when an electric current of 2mA flows through it. The resistance is _______ (rounded off to the nearest integer) Option: 1 2500 Option: 2 3000 Option: 3 400 Option: 4 5000

$\begin{array}{l} Q=i^{2} R T \\ \\ \Rightarrow R=\frac{Q}{i^{2} t}=\frac{10 \times 10^{-3}}{4 \times 10^{-6} \times 1}=2500 \Omega \end{array}$
