a electric fire is connected to the city power grid (120 V) it draws a current of 6A what is its power rating?

Respuesta :

Answer:

  • 720 Watts

Explanation:

Given:

  • Voltage (V) = 120 V
  • Current (I) = 6A

To Find:

  • Power (P)

Solution:

We know that electrical power is product of Voltage and current. So, Power formula is given by:

[tex] \\ \: \: \: \dashrightarrow \sf \: \: \: \underline{\boxed{\sf{ Power = Voltage \times Current}}} \\ \\ [/tex]

On substituting the required values, we get:

[tex]~~~\dashrightarrow~~~~[/tex] Power = 120 V × 6 A

[tex]~~~\dashrightarrow~~~~[/tex]Power = 720 watts

Hence,

  • Power rating is 720 Watts
