If it takes 3400J to lift a rock onto a ledge, what power is required to lift the rock onto the ledge in 4 seconds
Power is energy per unit time. It is measured in watts (joules per second).
As such if 3400 joules is transfeered in 4 seconds, the power equals 3400 / 4.
The power required is therefore 850 watts.

Is voltage energy or power?
Power is the rate of energy transfer. Since a power station require energy source to generate electrical power and as the engine horse power would first required combustion of fuel, it is energy that give power. Answer: power is the rate at which energy is converted. So a 100 watt light used for 2 hours would use the same energy as a 200 watt light for 1 hour.

Why some appliances perform quite when long extension cord are used?
An appliance which does not use much current will perform satisfactorily with a long extension cord. Any device which uses a lot of power (space heater, large power tools) will not perform well on a long ext cord unless the cord is large enough and rated to carry the required power.
What is electrical pressure?
Electro motive force = EMF = Voltage.
How many amps are required to run a 240-volt 5500-watt water heater element?
Current (Amps) = Power (Watt)/Voltage (V) Therefore a 4500W heating element will draw 18.75A = 4500W/240V

300 W
How much power is needed to perform 900 Joules of work in 90 seconds?
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
What is the power rating of a machine to lift a crate in 5 seconds?
That really depends on the weight of the crate. Also, on how high you want to lift it. Calculate the energy required to lift the crate with the formula for gravitational potential energy: PE = mgh (mass x gravity x height) Then divide this by the 5 seconds to get the minimum power required. (The actual power is somewhat larger, for various reasons - the initial acceleration required, and losses due to friction.)

5 seconds of rapid bell ringing
How much power is required to do 40 J of work on an object in 5 seconds?
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
