The symbol for a wire is simply a line between circuit elements. The symbol for a resistor is a squiggly line. The related link goes directly to a picture of the symbol.

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.


How does length affect resistance of a wire?

In general, the longer the wire, the greater the resistance. This is because a longer wire offers more resistance to the flow of electrons compared to a shorter wire. The resistance of a wire is directly proportional to its length.


What will you need to measure to find out which wire has the greatest resistance?

To find out which wire has the greatest resistance, you will need to measure the resistance of each wire using a multimeter. Connect the multimeter to each wire separately and record the resistance values displayed. The wire with the highest resistance value will have the greatest resistance.


How does the thickness of the wire affect resistance?

A thicker wire has less resistance than a thinner wire.


A 4 ohm resistance wire is doubled on it calculate the new resistance of the wire?

The resistance of a wire is directly proportional to its length, so doubling the length will also double the resistance. Therefore, doubling the 4 ohm resistance wire will result in a new resistance of 8 ohms.


Which has the lowest resistance thin wire or thick wire?

A thin wire will have higher resistance than a thick wire. This is because resistance is inversely proportional to the cross-sectional area of the wire - a thicker wire has a larger cross-sectional area compared to a thin wire, so it offers less resistance to the flow of current.


Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?

No, the wire with a diameter of 0.01 mm will have higher resistance compared to a wire with a diameter of 0.1 mm. Resistance of a wire is inversely proportional to its cross-sectional area, so a thinner wire will have higher resistance.


When a wire is made thicker it resistance?

When a wire is made thicker it's resistance decreases.


What three things affect the resistance in a wire?

The three main factors that affect the resistance in a wire are the material of the wire (different materials have different resistivities), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance).


What are three things resistance of a wire depends on?

The resistance of a wire depends on its length - longer wires have higher resistance. It also depends on the material of the wire - materials with higher resistivity have higher resistance. Lastly, the cross-sectional area of the wire affects resistance - larger cross-sectional areas have lower resistance.


Is a wire thick with low electric resistance?

A wire that is thicker than another wire of the same material has less resistance


What are 4 things that influence resistance in a wire?

The four main factors that influence resistance in a wire are the material of the wire, the length of the wire, the cross-sectional area of the wire, and the temperature of the wire. These factors determine how easily electrons can flow through the wire and affect its overall resistance.
