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?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
How does the thickness of the wire affect resistance?
A thicker wire has less resistance than a thinner wire.
How does the thickness of wire affect the resistance?
A thicker wire has less resistance than a thinner wire.
How does the resistance of a wire vary with its length?
resistance of wire increases with increases of length
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
How does length affect resistance of a wire?
In general, the longer the wire the greater the resistance. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.
When a wire is made thicker it resistance?
When a wire is made thicker it's resistance decreases.
Does a longer wire equal resistance?
Wire is not equal to resistance. If you have two pieces of wire with the same thickness, composition, and temperature, the longer piece has higher electrical resistance.
Is a wire thick with low electric resistance?
A wire that is thicker than another wire of the same material has less resistance
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
Which has the greater resistance thick wire or a thin of the same length?
The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
