What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
Why does the electrical resistance of a wire decrease when the wire is made shorter?
Using an analogy is the best way to explain this. Think of electrical current as cars on a road. The cars all want to get to their destination (which in a complete circuit is just to go in a loop) in the shortest time possible. As the road get's shorter the time it takes for the car to reach it's destination decreases.
Is a short wire better at conducting electricity?
In general, shorter wires are better at conducting electricity because they have less resistance compared to longer wires. Resistance in wires causes energy loss in the form of heat. So shorter wires are more efficient at conducting electricity.
Why does the build with a shorter wire give more brighter than the longer wire?
A shorter wire has less resistance, which allows more current to flow through the circuit, leading to a brighter output. However, using a shorter wire can sometimes cause overheating issues due to increased current flow. It is important to ensure that the wire gauge and circuit design can handle the higher current with a shorter wire.
Why does the current increase when the wire is shorter?
When the wire is shorter, the resistance decreases because there is less wire for the current to flow through, leading to a higher current for a given voltage. This is described by Ohm's Law (I = V/R), where current (I) is inversely proportional to resistance (R) for a constant voltage (V).

When you push down on a string to make it shorter what happens to the wavelength?
The wavelength gets shorter.
What happens to the shorter side of the isosceles triangle?
Nothing happens; it remains the shortest side forever!
When a wave legth get shorter what happens to the freqency?
Gets higher
What happens if the Earth spun faster?
The days would be shorter.
What happens to leg bones when you get older?
Legs get shorter and .brittle
What happens to thewavelenght if you increase the frequency of a wave?
Gets shorter.

Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
Why does a light BURN out?
Because the tungsten filament is evaporating. As the filament becomes thinner, resistance and temperature become higher, evaporation speeds up. Eventually the filament becomes so thin that it melts. A 100 watt incandescent light bulb radiates 98 watts of heat and 2 watts of light. In summer, it takes 50 watts of air conditioning to get rid of the 98 watts of heat. A 20 watt compact fluorescent produces the same 2 watts of light while consuming 85% less electricity, and absence of heat makes it last ten times longer.
What happens to the wavelength of an ac cycle if the frequency incresases?
It becomes shorter.
What happens to the length of day as you move north of the equator?
They become shorter.
