What might happen if a wire in an electronic device is replaced with a thinner longer wire explain?

If you use the same battery but replace a thick wire with a thinner one, the electric current will get smaller and a light bulb in the circuit should get dimmer. Using a longer wire will also increase resistance. The thinnest piece of wire you used, the 20 gauge, is less than a millimeter thick, which may seem small.

What will happen if the wire is thinner?

The thin wire will conduct electricity, but there is more electrical resistance. The thicker wire is like the four lane highway. There’s a lot less electrical resistance, and as a result, that light bulb burns brighter because more electricity can reach it.

How does the material of a wire affect resistance?

The thicker the wire, the lower the resistance. (3) Material: the material the wire is made out of will affect the resistance. Different materials have different resistivities, which is the ability of the material to allow electrons to move. It is dependent on electronic structure and temperature.

How does the diameter of a wire affect conduction of electricity?

The less heat the wire produces, the lower its temperature will be while operating. Therefore a larger-diameter wire will be able to carry a larger current before it heats up enough to melt or scorch its insulation or ignite other objects near it.

What is the effect of changing the wire in a circuit from a thick wire to a longer coiled thick wire?

16 Cards in this Set

In a simple series circuit, why does the bulb light when you close the switch?	Because closing the switch completes the circuit.
What is the effect of changing the wire in a circuit from a straight thick wire to a straight thin wire?	The bulbs become dimmer.

How does increasing the length of a wire affect its resistance?

The resistance is directly proportional to the length of the wire, the longer the wire the greater the resistance. Well the longer the wire the more collisions the electrons will have with the atoms in the way from one end of the wire to the other. Therefore the resistance will increase as the length increases.

Does a longer wire increase voltage?

Adding extra cable will cause a voltage drop at the load so the current drawn will increase. Anything is possible, depending on the type of load: current may decrease, increase or stay the same.

What happens when you put a thinner wire in a circuit?

A piece of thin wire has higher resistance than a piece of thicker wire with the same length, which means that it’s harder for electric current to move through it. If you use the same battery but replace a thick wire with a thinner one, the electric current will get smaller and a light bulb in the circuit should get dimmer.

Why does a longer wire have a lower resistance?

A light bulb requiring X watts will have lower resistance if the voltage across it isn’t ideal. The lower resistance allows higher current. To summarize: longer wire = higher resistance = lower voltage at load = lower resistance load = more current through wires = greater chance of starting fire.

Why are thin wires better than thick wires?

Here’s why: First, a little background that you may already know. A piece of thin wire has higher resistance than a piece of thicker wire with the same length, which means that it’s harder for electric current to move through it.

What happens when you double the length of a wire?

Then we run a certain amount of current though it which will produce heat in the wire. Now we double the wire length to 2m, so double the resistance. We run the same current through it which will produce double the amount of heat, but over double the amount of length.
