You don't specify what you are referring to. However, if your question relates to resistance in general, then you should know that resistance is directly-proportional to the length of a conductor and to its resistivity, and inversely-proportional to its cross-sectional area. Resistivity is a characteristic of the material from which a conductor is made, and varies from one material to another.
This means that you can increase resistance by increasing the length of a conductor, or by decreasing its cross-sectional area, or by selecting a conductor manufactured from a material with a greater resistivity (e.g. by using aluminium rather than, say, copper).

∙ 10y agoWithout physically changing the material of the wire, the only one way I can think of is to Heat the wire. I am not considering the wire's length since your question implies a specific piece of wire.

What are two ways to alter the wire to increase the resistance in the electric circuit?
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
What increases resistance in a wire?
Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.
How do you know the voltage drop of wire?
Voltage = Current x Resistance. To calculate the voltage drop of a piece of wire, you would have to know the current flowing in the circuit and the resistance of the wire. The resistance of wire depends on the material it is made of, the length, and the cross sectional area (also called gauge or AWG). Short thick wires have less resistance than long thin wires. You can look up the resistance of the wire on the Internet, and you can measure the current flowing by connecting an ammeter in series with the circuit. Multiply those two numbers and you will have closely approximated the voltage drop across the wire.
When two lengths of the same uniform wire are connected..................the effective resistance is the sum of the separate resistances.Full in the space?

What are two ways you could alter the wired to increase the resistance in the electrical circuit?

What is the effect on its resistance if a resistive wire is elongated?
There are two ways to elongate a piece of wire: Either stretch it, or attach another piece onto one end of it. Either way, the resistance will increase.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
How do you increase resistance?
Since resistance is the ratio of voltage to current, if the voltage is constant then increasing the resistance will result in a reduction in current.
Two ways resistance of a wire can be increased?
The resistance of a wire is determined by the following formula. R = (rho)L/A, where the greek letter rho (it looks like a p) is a value assigned to a material based on how resistive it is by nature, L is the length of the wire, and A is the cross-sectional area (AKA how thick the wire is). Increase the length, or change the material to something with higher restistivity. Hope this helps!

What are the two ways of decreasing current in a standard test circuit?
Increase the resistance (ohms) Decrease the voltage (Volts)
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 there a direct correlation between increase in coil wraps and electrical resistance of a guitar pickup?
There is a direct relationship between the length of wire (thus the number of times the wire is wrapped) and the electrical resistance of the guitar pickup, measured at the two output terminals.
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
Describe two ways to increase the current in a circuit?
1. Increase the voltage while holding the resistance constant.and2. Decreasing the resistance while holding the voltage constant.For a fixed load, increase the supply voltage. For a fixed supply voltage, increase the load.So that there is no confusion, 'increasing a load' means reducing the resistance (in the case of a d.c. circuit) or reducing the impedance (in the case of an a.c. circuit).
