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

Options:

Answer:

Solution:

$500 = (1.5)^{2} \times R \times 20$

$E = (3)^{2} \times R \times 20$

$E = 2000 J$
