Question

Energy consumed in a heater is 5000 J in time 2 s . The power of the heater is *​

Answer 1

Explanation:

Energy is 5000j,time taken is 2s.So,the power is,

p=E/t= 5000/2=2500W.

Answer 2

Answer:

• Power of the heater is 2,500 W

Given:

• Energy consumed = 5,000 J
• Time elapsed = 2s

Explanation:

$\rule{300}{1.5}$

From the formula of power we know,

$\bigstar\ {\underline{\boxed{\sf{Power\ =\ \dfrac{E}{t}}}}}$

Here,

• E denotes energy consumed.
• t denotes time elapsed.

Substitute the respective values,

${\longrightarrow{\sf{Power\ =\ \dfrac{E}{t}}}} \\ \\ \\ {\longrightarrow{\sf{Power\ =\ \dfrac{5,000}{2}}}} \\ \\ \\ {\large{\longrightarrow{\underline{\boxed{\sf{\red{Power\ =\ 2,500\ W}}}}}}}$

∴ The power of the heater is 2,500 W.

$\rule{300}{1.5}$
