The power switch or button on a hair dryer controls when the current flows through the device. It allows the user to turn the hair dryer on and off by completing or interrupting the electrical circuit, which determines whether the current flows through the device.

What current flows through a hair dryer plugged into a 120 volt circuit if it has a resistance of 25 ohms?

The current flowing through the hair dryer would be 4.8 amps (120 V / 25 Ω = 4.8 A).


How is energy produced in a hair dryer?

The heat can travel by the air/oxegyn.Electric can go by the wires/energy.


Is a hair dryer direct or alternating?

A hair dryer is powered by alternating current (AC) electricity. This type of current allows the hair dryer to function effectively by converting electrical energy into heat and air flow.


A hair dryer converts what type of energy to thermal energy?

A hair dryer converts electrical energy into thermal energy. When the hair dryer is turned on, electricity flows through a heating element, which generates heat that is then blown out of the dryer to dry the hair.


What kind of energy transformation is used in a hair dryer?

In a hair dryer, electrical energy is transformed into heat energy. The electricity flows through a resistor or coil inside the hair dryer, which generates heat due to resistance, and this heat is then used to dry and style the hair.


How does ohms law apply to a hair dryer?

Ohm's Law can be applied to a hair dryer to determine the relationship between the voltage supply, current flowing through the device, and its resistance. By knowing the voltage of the power source and the resistance of the hair dryer (typically indicated on the device), you can calculate the current flowing through the hair dryer using the formula I = V/R, where I is the current, V is the voltage, and R is the resistance.


How much current does a 120v 1200w hair dryer draw?

Using the formula Power = Voltage x Current, you can rearrange to solve for current: Current = Power / Voltage. Plugging in the values, the hair dryer would draw 10 amps of current (1200W / 120V).


What is the current in the hair dryer if it is plugged into a Outlet?

The current in a hair dryer plugged into an outlet in the US (120V) is typically around 10-12.5 Amps. In Europe (230V), it would be around 5-6 Amps.


2. A hair dryer converts what type of energy into thermal energy?

A hair dryer converts electrical energy into thermal energy. The electric current flowing through the hair dryer's heating element causes it to heat up, transferring thermal energy to the surrounding air which dries the hair.


A hair dryer uses 1.2 kW of power when it is plugged into a 120V outlet and is turned on What is the current taken by the hair dryer?

The formula you are looking for is I = W/E. W = kW x 1000.


What are some innovative ways to store and organize a hair dryer with a hair dryer mount?

Some innovative ways to store and organize a hair dryer with a hair dryer mount include using a wall-mounted hair dryer holder, a magnetic hair dryer holder, or a hair dryer caddy that can be attached to a cabinet or drawer. These options help keep the hair dryer easily accessible and out of the way when not in use.


When was the hair dryer invented?

the hair dryer was invented by Alexandre in 1890 but the first had held hair dryer was invented 1971.
