QUESTION 3 Suppose that you have a leaf blower that draws 1100 Watts in operation, It is fed by an extension cord that is plugged into a 120 volt outlet by two wires having a resistance of 0.15 ohms each. Because of that resistance, the voltage at the leaf blower is a bit less than 120 volts, but you can still assume that it runs on the same current it would if it were connected to a true 120 volt supply. How much power is dissipated in the extension cord? 25 watts 13 watts O 40 watts 63 watts O 20 watts
