A hair dryer is labeled as proudly using 1500 Watts. If you use it for 60 seconds, and it is plugged into a 120 V wall socket, how much current is flowing during operation?

The answer for the following question is explained below.

Explanation:

Power (P):

The rate of doing wok or f transferring the heat is called power.

Current (I):

The rate of flowing electric charge is called electric current.

Given:

Power (P) = 1500 watts

voltage (v) = 120 V

time (t) = 60 seconds

To calculate:

current flowing (I)

We know;

According to the formula;

we know;

P = V × I

where;

P represents the power

V represents the voltage

I represents the current

we know;

From the above problem;

1500 = 120 × I

 I =

 I = 12.5 amperes

Therefore the current flowing during the operation is 12.5 amperes

the total distance traveled by the car is

30km + 49km = 79 km .
