The cord from an appliance is too short to reach the wall outlet in your room. You have two extension cords to choose from. (a) Find the voltage drop in the first extension cord having a 0.0520 N resistance and through which 7.80 A is flowing. V (b) The second extension cord is cheaper and utilizes thinner wire. It has a resistance of 0.1040 and the current flowing through it is 7.80 A. By what amount does the voltage supplied to the appliance change when the first extension cord is replaced by the second?

The cord from an appliance is too short to reach the wall outlet in your room. You have two extension cords to choose from. (a) Find the voltage drop in the first extension cord having a 0.0360 resistance and through which 6.20 A is flowing. v (b) The second extension cord is cheaper and utilizes thinner wire. It has a resistance of 0.072 N and the current flowing through it is 6.20 A. By what amount does the voltage supplied to the appliance change when the first extension cord is replaced by the second?
The brightness of a lightbulb is dependent on the current that goes through the lightbulb (in reality on the power, which is I^2/R). In Europe, the voltage used is 220 Volts, as opposed to the 120 Volts used in the USA. Will a lighbulb that is made for European voltage work well or poorly in the USA? It will work poorly in the USA. Since I=V/R, if V decreases, so does I, and so does the brightness. It will work more efficiently in the USA. Since I=V/R, if V decreases, I increases, and the brightness increases. It will work better in the USA because the resistance of the wires is smaller. Whether it works better or worse depends on how modern the wiring system is, regardless of the voltage, V.
