What is the power produced by a light bulb with a voltage of $120V$ and a current of $0.045A$?

Which unit is most commonly used to measure electrical power?

A $1500$-$W$ heater is connected to a $120$-$V$ line for $2.0$ $\mathrm{hours}$. How much heat energy, in $\mathrm{joules}$, is produced by the heater during this time?

Which of the following best defines power in physics?

A $1500-W$ electric heater is connected to a $120-V$ power line. How much heat energy, in joules, does it produce in $2.0$ hours of operation?

Which of the following scenarios uses the most $\mathrm{power}$?

If a light draws $220W$ on a $120V$ circuit, what is the current flowing through the light?

If you move an $8-\mathrm{newton}$ weight a distance of $5 \mathrm{meters}$ in $4 \mathrm{seconds}$, how much power have you generated?

Power is defined as the rate at which work is done. What is the value of power in terms of work $W$ and time $t$?
