Question

Calculate the power of an electric device which supplies an energy of 180000 joule when used for 1 minute.​

Answer 1

Answer:

Given :

• An electric device which supplies an energy of 180000 Joule when used for 1 minutes.

To Find :-

• What is the power of an electric device.

Formula Used :-

$\bigstar$ Power Formula :

$\mapsto \sf\boxed{\bold{\pink{Power =\: \dfrac{Work\: Done}{Time\: Taken}}}}$

Solution :-

First, we have to convert minutes into seconds :

$\leadsto \sf Time\: Taken =\: 1\: minutes$

$\leadsto \sf Time\: Taken =\: 60\: seconds\: \bigg\lgroup \sf\bold{\pink{1\: minutes =\: 60\: seconds}}\bigg\rgroup$

$\leadsto \sf\bold{\purple{Time\: Taken =\: 60\: seconds}}$

Now, we have to find the power of an electric device :

Given :

• Work Done = 180000 Joules
• Time Taken = 60 seconds

According to the question by using the formula we get,

$\implies \sf Power =\: \dfrac{18000\cancel{0}}{6\cancel{0}}$

$\implies \sf Power =\: \dfrac{18000}{6}$

$\implies \sf Power =\: \dfrac{3000}{1}$

$\implies \sf\bold{\red{Power =\: 3000\: Watts}}$

$\therefore$ The power of an electric device is 3000 Watts.
