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.

What does power line carry voltage or current?
It carries a current at the set voltage of the line. Current is the actual electricity that flows along the line and is used up in your electric appliances whereas voltage is the difference between the energy being generated at the station and ground.AnswerIt carries both voltage and current. Voltage exists between each line conductor, and current flows through each line conductor.
Can You power a city on a bolt of lightning?
No, a single bolt of lightning does not contain enough energy to power an entire city. Lightning strikes have a very high voltage but their duration is very short, and the total energy produced is not sufficient for powering a city for an extended period of time.
Which condition refers to a sudden and dramatic increase in voltage which usually caused by lightning?
A sudden and dramatic increase in voltage typically caused by lightning is known as a power surge. Power surges can damage electrical equipment and appliances if they are not properly protected by surge protectors or other safeguards.
What is a device that transforms electrical energy?
A battery or a fuel cell converts chemical energy directly to electrical energy
How is energy and power related?
Power is the rate at which energy is transferred from one object to another or converted from one form to another.
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
Can the amount of energy carried by a power line be increased by raising voltage?
The energy supplied by a power line is determined by its load, not by its voltage. For a given energy demand by its load, the higher the liine's voltage, the lower the resulting load current.
What is the electrical voltage are supplied by the power supply on your system?
The electric voltage are energy to my system.
How does electricity energy produced?
Power is calculate by the formula P = IV (current x voltage); energy of course is power x time, so you have energy = IVt (currnt x voltage x time).
How much energy does electricity produce?
Power is calculate by the formula P = IV (current x voltage); energy of course is power x time, so you have energy = IVt (currnt x voltage x time).
What provides energy to circuit?
One possibility for what affects the voltage, is how many light bulbs, motors etc you have in the circuit causing the energy ( voltage ) to be shared.
What is the role of voltage in an electrical circuit?
Voltage is related to energy by charge. Power equals voltage times current (amperes), and energy equals voltage times charge (coulombs).An ampere is 1 coulomb of charge moving per second.A watt (power) is 1 joule of work done (or energy transferred) per second.
How do yo calculate electric power and energy use?
Power = voltage x current Number of power in volts
How many AH equals to 1KVA?
You really can't compare that. * Ampere-hour is a unit of energy. If you multiply ampere x hours x voltage (the voltage is implied), you get energy. * kVA is a unit of power. Note that power is energy / time.
How does energy get from a power plant to your home?
Energy gets from the power plant to customers via the power grid (high voltage power lines).Transmission lines that generally operate at high voltages are responsible for long distance delivery of electricity. Substations step the voltage down to deliver it locally, and Transformers further step down the voltage to deliver it to the customer.Note: There are no energy transformations invloved in this process. The power plant (whatever kind it might be) produces electricity (electromagnetic energy), and this is delivered to a user via the power grid. For energy transformation in power plants, refer to those specific questions.
How does voltage and current work together to produce power?
That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.
Why is energy lost in power transmission lines?
Increase the voltage in the lines.
