How does temperature affect resistance of a wire?
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
A wire with resistance R is connected to the terminals of a 30 V battery. What is the current through the wire if the wire has the resistance?
Your current will be 30/R Amps. Where R is the resistance in Ohms.
Items that use low resistance wire?
Ni chrome is a low resistance wire used in heaters and toasters.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
Would thick wires tend to have the least amount of eletrical resistance?
Yes, the resistance is directly proportional to length of wire and inversely proportional Area, hence when Length of wire increases the resistance also increases and when Area increases the resistance decreases. This means a thick wire has least amount of Electrical resistance.
What re the difference between slide-wire rheostat carbon rheostat and resistance box.?
Slide wire rheostat: We can get continuous variation in resistance. It is used in such situations where we are supposed to get a fixed current flowing throug the circuit-some integral value like 1,2 etc instead of 1.343 and all. Resistance box: It is a deveice used to get a specific value of resistance. We may not get a simple value for current.
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.
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 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.
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.
Can you use copper wire instead of eureka wire in finding its resistivity?
Yes, you can use copper wire instead of eureka wire to determine resistivity by measuring its resistance, length, and cross-sectional area. However, keep in mind that the resistivity values for copper will be different from eureka wire, so you will need to account for that difference in your calculations.
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.
When a wire is made thicker it resistance?
When a wire is made thicker it's resistance decreases.
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.
How do you make a simple electromagnetic device?
you dont, just take a nail and a wire and put it together with a battery.
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).
