How many joules of energy will a 3.8 W lamp dissipate in 10 minutes? Answer: OkJ

Question

UpStudy AI · Accepted Answer

Given:
- Power of the lamp: $$ P = 3.8 \, \text{W} $$ (where $$1 \, \text{W} = 1 \, \text{J/s}$$)
- Time: $$10$$ minutes

**Step 1: Convert time to seconds**

Since $$1$$ minute $$= 60$$ seconds,  
$$
10 \, \text{minutes} = 10 \times 60 = 600 \, \text{seconds}
$$

**Step 2: Use the energy formula**

The energy dissipated can be calculated using:
$$
E = P \times t
$$
Substitute the given values:
$$
E = 3.8 \, \text{W} \times 600 \, \text{s}
$$

**Step 3: Calculate the energy**

$$
E = 3.8 \times 600 = 2280 \, \text{Joules}
$$

The lamp dissipates $$2280$$ joules of energy in 10 minutes.
The lamp dissipates 2280 joules of energy in 10 minutes.
