Power Calculator

Top
Power calculator helps to determine the power of an object in terms of its work with respect to the time. Power is denoted by P and the unit is watts. The mathematical expression for power is given as,

$P$ = $\frac{W}{T}$

Where P is the power
          W is the work
          T is the time

Let us discuss the problems related to the power.

Solved Examples

Question 1: Calculate the power of an object whose work done is given as 50J ant the time taken is 20s?

Solution:
 
Given that,
W = 50J, T = 20s
Power formula is,

P = $\frac{W}{T}$

P = $\frac{50}{20}$ = 2.5watts

 

Question 2: The work done in 5s is given as 12J.Calculate the power?

Solution:
 
Given that,
W = 12J, T = 5s
Power formula is,

P = $\frac{W}{T}$

P = $\frac{12}{5}$ = 2.4watts
