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

**Step 1:**Identify the given parameters .

**Step 2:**Plug these variables in the given equation and find out the unknown variable .

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

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
