What does the electrical power dissipated in an appliance depend on?

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?
what is the power rating of energy
What determines whether a 100-W light bulb costs 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.
The MAIN purpose of the grounding pin in a three prong plug for appliance is to what?
It is to prevent electrical shocks.
An appliance plug can be distinguished from other plugs by its?
permanent attachment to an appliance An appliance plug may have a differently shaped plug, in order to prevent it from being plugged into an ordinary electrical outlet (one with the wrong voltage or power rating).
Why do electrical appliances need to be plugged into the wall?
Because the power needed to make them work is delivered by a national 'grid' of electrical cables. There is no way to actually transmit power to an appliance through the air. It must be deilvered by cables.
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 does the power rating of an electrical appliance mean?
what is the power rating of energy
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 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'.

If current in an electric stove is doubled how will the thermal energy produced per unit time change?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
What may cause an electrical conductor to heat up?
An electrical conductor may heat up due to excessive current passing through it, which increases its resistance and generates heat. Poor connections, overloading, or inadequate conductor size can also cause heating. This can lead to a potential fire hazard if not addressed.
