Question

An electric bulb consumes 3600 j of energy in 1 minute . Calculate its power

Answer 1

$\textbf{\huge{ANSWER:}}$

$\mathfrak{Energy}$

The capacity to do work is known as Energy. The value of Work and Energy is same. Work is denoted by W, while Enegy is denoted by E.

$\mathfrak{Power}$

The work per unit time is termed as Power. Power is denoted by P.

The formula of Power is:

$\frac{Energy}{Work}$

The values we're given with:

Energy = 3600 J

Time = 1 minute

In the Formula, the SI Units of Energy and Time are Joules (J) and Seconds (s) respectively.

So, we need to convert the given time in seconds.

Time in seconds = 1 × 60 = 60 s

Putting the given values in the Formula:

$\frac{3600}{60} \\ \\ = 60$
Therefore, the Power = 60 Watt.

Hope it Helps!! :)

Answer 2

$\huge\textbf{Answer}$


An electric bulb consumes 3600 J of energy in 1 min.

Here;

Energy = 3600 J

and

Time = 1 min

= 60 sec

We have to find Power.

Now

Power = $\dfrac{Energy}{Time}$

= $\dfrac{3600}{60}$

= 60

So,

$\textbf{Power is 60 Watt.}$

Here, Watt is the S.I. unit of Power.
