Question

What is the power of a hair dryer that uses a 230 V power supply if 5 A of current flows through it?

Answer 1

Answer:

Here ,

V=230

I=5

P=?

so , we know that

P=VI

P=230 ×5

1150 ans

Answer 2

Answer:

The power of the hair dryer is 1150 W (230 V x 5 A = 1150 W).

Explanation:

Power is the rate at which labor is completed or energy is transformed between different forms. Watts (W) or horsepower are used to measure it (hp). The amount of work completed, the time required to complete the work, and the amount of energy used are all related to power. The passage of electric charge via a conductor, such as a wire, is known as current. Electric current is expressed in amperes (amps), which are used to measure it. A unit of power, the watt (symbol: W), is one joule of energy every second. It is typically used to gauge how quickly energy is moving. The capability to perform work is referred to as energy. The measurement unit for power is called a horsepower of an engine or motor. It is typically stated in terms of horsepower (hp).
