Machines a, b, and c do the same amount of work, but they each take a different amount of time. machine a takes more time as compared to machine c. machine b takes the maximum time to do the same amount of work. which machine expends the most power doing this work?

Machine C is producing maximum power

Explanation:

As we know that power is defined as rate of work done or rate of energy produced.

Here it is given that we have three machines A , B  and C

All three machines are doing same amount of work but the time taken by the machines is different.

Here given that maximum time is taken by machine B and then out of A and C it is given that machine A took more time than machine C.

So here we know from above relation that lesser the time more will be the power so here maximum power is due to Machine C as it is doing same work in least amount of time.
