Question

how much energy is consumed in one minute by a 100 w bulb? multiple choice 10 kj 100 j 6000 j 600 j

Explanation:

Step1: Recall power - energy formula

Power $P=\frac{W}{t}$, where $P$ is power, $W$ is energy, and $t$ is time. We want to find $W$, so $W = P\times t$.

Step2: Convert units

The power $P = 100\ W$, and the time $t=1\ minute = 60\ s$.

Step3: Calculate energy

Substitute the values into the formula: $W=P\times t=100\ J/s\times60\ s = 6000\ J$.

Answer:

C. 6000 J
