Question

what is the answer please!​

Answer 1

Answer:

I think B. 10kj is your answer

Answer 2

Required Solution:

${\underline {\boxed {\huge {\sf \pink { Option \: A (1KJ) } }}}}$

Given:

• Resistance (R) = 50Ω

• Current passing (I) = 2 A

• time taken (t) = 5 s

To calculate:

• Heat energy produced (H)

Calculation:

We know that,

• ${\underline {\boxed {\large {\rm {H = {I}^{2} Rt} }}}}$

Where,

• I² = Square of current
• R = resistance of wir
• t = time taken

Substitute the values:

$\sf { ⇢ H = {2}^{2} \times 50 \times 5}$

$\sf { ⇢ H = 4 \times 50 \times 5}$

$\sf { ⇢ H = 200 \times 5}$

$\sf { ⇢ H = 1000 J}$

Therefore, heat energy produced is 1000 J or 1KJ
