Q = i 2 RT R =( Q / i 2 t )=(10 × 10-3/4 × 10-6 × 1)=2500 Ω

Q. The energy dissipated by a resistor is $10 m J$ in $1 s$ when an electric current of $2 m A$ flows through it. The resistance is ____________ $Ω$ (Round off to the Nearest Integer)

$Q = i^{2} RT$

$R = \frac{Q}{i ^{2} t} = \frac{10 \times 1 0 ^{- 3}}{4 \times 1 0 ^{- 6} \times 1} = 2500 Ω$

Q. The energy dissipated by a resistor is 10mJ in 1s when an electric current of 2mA flows through it. The resistance is ____________ Ω (Round off to the Nearest Integer)

Q=i2RT R=i2tQ​=4×10−6×110×10−3​=2500Ω
