The Nichrome Heating Element in an Electric Drier Operates on 240

question 189

Multiple Choice

The nichrome heating element in an electric drier operates on 240 V and generates thermal energy at the rate of 2.0 kW.The heating element shorts out and,in repairing it,the repairman shortens the nichrome wire by 10%.(Assume the temperature is unchanged.In reality,the resistivity of the wire will depend on its temperature.) What effect will the repair have on the power dissipated in the heating element?

• A)The power is still 2.0 kW.
• B)The power increases to 2.2 kW.
• C)The power decreases to 1.8 kW.
