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
Now by putting the values in the above equation we get
R= 20 ohm
Therefore the resistance of the steam will be 20 ohm.
