All electric devices are required to have identifying plates that specify their electrical characteristics. The plate on a certain steam iron states that the iron carries a current of 6.00 A when connected to a source of 120 V. What is the resistance of the steam iron?

Respuesta :

Answer:

R= 20 ohm  

Explanation:

Given that

Current ,I = 6 A

Voltage difference ,ΔV = 120 V

Lets take resistance of the stem iron = R

We know that ,the relationship between current ,voltage difference and resistance is given as

ΔV = I R

[tex]R=\dfrac{\Delta V}{I}[/tex]

Now by putting the values in the above equation we get

[tex]R=\dfrac{120}{6}\ ohm[/tex]

R= 20 ohm

Therefore the resistance of the steam  will be 20 ohm.
