A resistor develops $500 \mathrm{J}$ of thermal energy in $20 \mathrm{s}$ when a current of $1.5 \mathrm{A}$ is passed through it. If the current is increased from $1.5 \mathrm{A}$ to $3 \mathrm{A}$, what will be the energy developed in $20 \mathrm{s}$.

• A

  $1500 \mathrm{J}$
• B

  $1000 \mathrm{J}$
• C

  $500 \mathrm{J}$
• Correct answer
  D

  $2000 \mathrm{J}$

Hence, the correct answer is option: 'D'.
