A short, thick, cold wire is the best conductor. A shorter wire will allow electricity to move through at a higher rate than a longer wire. How well a material conducts current is an internal factor affecting resistance. If you double the length of a wire, you cut the resistance in half. If you double the thickness of a wire, you cut the resistance in half. Superconductors have no measurable resistance. The higher the temperature of the conductor, the lower the resistance. The resistance in a wire with less thickness is less. Thickness, length, and temperature are internal factors that affect resistance. When a light is first switched on, the light bulb's filament has a lower resistance than after it gives off light for awhile.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
