So now on to energy and power! So how are work, energy and power connected here? Also when you get a bill form the electric company, are you paying for energy or power? Why does this matter?

Answer #1

Solution:

A)

Work: refers to an activity involving a force and movement in the directon of the force.

Energy: is the capacity for doing work.

Power: is a measure of how quickly work can be done. P = E/t.

B)

The bill from the electric company states the Power [in kWh] we consumer.

C)

This matters beacuse, If we are using one kW of power, a kW of energy will last one hour.

The unit of power is the Watt = 1 Joule/ 1 second.

One common unit of energy is the kilowatt-hour (kWh).

I hope you understood the problem, If yes rate me!! or else comment for a better solution.

An initially uncharged 12 μF capacitor charged by a 12 V power supply (battery) connected in series with a 100 Ω resistor. i. What is the total energy stored in the capacitor when it reached the fully charged situation? ii. What is the total energy supplied by the power supply during this time? iii. Does the capacitor store the total energy supplied by the battery? Otherwise, explain how the energy supplied by the battery used in the circuit.

Suppose you need to control the speed of a motor that takes 1200W at full power. This is typical of a big domestic vacuum-cleaner or a washing-machine motor, and is a little more power than a single-bar electric fire uses. First, you try the obvious method: a variable resistor in series, and no other complications. If you adjust the resistor to have a very high value so little current passes, this will make the motor run very slowly or stop....

If you slide a block along a frictional surface, you do work against friction. Suppose you smack the block so that it slides along for a while, but comes to a stop. The block started at rest and ends up at rest, but you’ve done work. Does the work-energy theorem fail, here? If so, why? If not, where did the energy go?
