(a) Find the voltage drop in an extension cord having a 0.062 resistance and through which 4.5 A is flowing. V= V (b) A cheaper cord utilizes thinner wire and has a resistance of 0.35 2. What is the voltage drop in it when 4.5 A flows? V= V (c) Why is the voltage to whatever appliance is being used reduced by this amount? What is the effect on the appliance? The voltage supplied to whatever appliance is being used is reduced because the total voltage drop from the wall to the final output of the appliance is So, if the voltage drop across the extension cord is large, the voltage drop across the appliance is significantly so the power output by the appliance can be significantly reducing the ability of the appliance to work properly. Find the power dissipated in each of these extension cords: (d) an extension cord having a 0.06 2 resistance and through which 4.5 A is flowing; P= W
