Power is then directly proportional to the work done and inversely proportional to the time to do the work. Remembering that work is force times displacement (W = F*d), you can derive a corollary for the power equation. Substituting this formula into the power equation we get P = F*d/t.

Data: Equation: Substitute: Calculation: Answer: ELECTRICAL POWER (P) - is a measure of the rate at which energy is being used - how rapidly an appliance is using up . energy - power is measured in WATTS (W) - 1 W = 1 J/s. If you left a 300 W light bulb and a 100 W light bulb on for one hour, the 300 W light bulb would use 3 times more energy.

Electrical circuits consist of the following components: an energy source to provide voltage, conductors to allow current travel, insulators to limit current travel, and a load. Electrical circuits provide an uninterrupted path for current travel and are broken into two distinct categories of design: series circuits and parallel circuits.

7. We know that we want the student to be able to generator 50,400J of energy, and the problem says they can continuously produce 30W of power which is 30J/s. Use the given information and the power equation to solve for the time (Δt): P = ΔE/t, 30J/s = 50,400J/Δt, solving for Δt = (50,400J) / (30J/s) = 1,680s or. 28min.
