The amount of power required to run an electric appliance depends on how many kilowatts of power it uses. The cost to run the appliance depends on how much your company charges per kilowatt.
<<>>
The amount of power depends on how much power it was designed to take. Some appliances are designed to take as little as possible, like radios, TVs and computers.
Others are designed to turn electric power into another form of power, like mechanical power (motors) or heat power (space heating). These tend to use more power.
The amount of energy paid for via the bill depends on the sum of the energy used by all the appliances. For each appliance it's the power drawn multiplied by the time it was used.

What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
What does an electric appliance use up in its operation?
An electric appliance uses up electrical energy during its operation to power its components and perform its intended functions. This energy is typically supplied through a power source such as an electrical outlet or battery.
What happens if power rating of an appliance is exceeded?
Exceeding the power rating of an appliance can lead to overheating, electrical fires, or damage to the appliance. It can also trip circuit breakers or blow fuses in your home's electrical system. It is important to only use appliances within their specified power ratings to ensure safe operation.
What is an appliance cord?
An appliance cord is a flexible electrical cable that connects an appliance to a power source. It typically has a plug on one end for connecting to an electrical outlet and is wired to the appliance on the other end. These cords come in different lengths and designs to suit various appliances' power needs.
How is it possible to use more than one electrical appliance at a time?
It is possible to use more than one electrical appliance at a time by connecting them to separate outlets or power sources. Each appliance will draw power from the source it is connected to, allowing multiple appliances to operate simultaneously without overloading a single circuit.
What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
What is the definition of power cord?
A cord to conduct power to an electrical appliance.
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
What is the function of electrical socket?
Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
What does an electric appliance use up in its operation?
An electric appliance uses up electrical energy during its operation to power its components and perform its intended functions. This energy is typically supplied through a power source such as an electrical outlet or battery.

What is the power dissipated by a parallel resistor of 100 ohms with a 40v power source?
You may find it helpful to use Ohm's law and the definition of electrical power.
Why does the heating effect of an electric current depends on the electrical resistance of a conductor?
The power dissipated by a resistance 'R' carrying a current 'I' is [ I2R ]. The power is dissipated as heat, and you can see from [ I2R ] that for a given current, it's directly proportional to 'R'.
What determines whether a 100-w light bulb cost more to use than a 1200-w hair dryer costs to use?
The electric power used by an appliance is the rate at which the appliance converts electrical energy to other forms of energy. The electrical energy used by an appliance depends on the power of the appliance and the length of the time it is used.
What is the equation for energy transferred by an electrical appliance?
The equation for energy transferred by an electrical appliance is given by: Energy (in joules) = Power (in watts) x Time (in seconds)
