Question

Extra (1): A hair dryer bears the inscriptions(220V-1500W)

a. What do these inscriptions mean?
b. What current would it carry in normal functioning?​

Answer 1

See the answers below.

Step-by-step explanation:

a)

The dryer plate indicates that the estimated power is 1500 [W] and operates connected to the mains with an electrical voltage of 220 [V]

b)

The electrical current is determined by the following expression:

`P=V*I`

where:

V = voltage = 220 [V]

I = current [amp]

P = power [W]

`1500=220*I\\I=6.81[amp]`
