View Full Interview# What will happen if the resistance of the conductor increased?

Assuming that there is a potential difference across the conductor, then the value of the current will fall (I = E/R).

# What will happen to the resistance of a wire if it is stretched to increase its length by 2 times?

Actually resistance is directly proportional to the length provided area remains constant. But as we stretch the wire only its volume would remain constant. So its area is to …be decreased as length increases. V = pi r^2 * L Now we have R = K * L / pi r^2 Multiplying numerator and denominator by L we get R = K/V * L^2 So resistance is found to be proportional to square of length Hence as length gets increased by 2 times, its resistance value would increase by 4 times.

# What happens to the resistance of a conductor wire as the temperature of the wire increases?

It increases

# What will happen to the brightness of a bulb if the length of a wire increases?

If you mean the length of the wire that supplies current to the bulb, the bulb will dim due to increased resistance in the wire, if you make it longer.

# What happens to the resistivity of the material of wire when the diameter of a metal wire is doubled keeping the length same?

Nothing. Resistivity, expressed in ohm metres, is a constant for any particular conductor although it is affected by temperature.

# What happens to voltage when resistance is increased?

When we increase the resistance the voltage is also increases.........

# Suppose a wire of resistance R could be stretched uniformly until it was twice its original length. What would happen to its resistance?

Current tends to travel on the surface of the wire. As you decrease the cross-sectional area of a wire the resistance increases. That is why larger wires are rated for higher …currents.

# A piece of wire is stretched such that its length increases and its radius decreases the resistance of the wire will tend to?

A piece of wire stretched such that its length increases and its radius decreases will tend to have its resistance increase. The formula for this is: R = ρL/A where ρ = re…sistivity of the material composing the wire, L = length of the wire, and A = area of the conducting cross section of the wire. It can easily be seen that as area decreases resistance gets higher. In the case proposed the wire length is not reduced as it is stretched to reduce the area, this increases the resistivity as well.

# What happens to resistance when resistors are wired in parallel?

Total resistance in the circuit decreases Two resistors in parallel have less overall resistance than the same two resistors in series, or even just one of the resistor…s by itself. This is because two resistors in parallel draw more current than just one resistor -- assuming constant voltage. If the voltage remains constant and the current increases, then Ohm's Law (V=IR) dictates that the resistance must decrease. When you have resistors in parallel, you can compute the total resistance fairly easily with simple math. The special case of having two resistors in parallel is interesting and easy to remember. To compute the total (or apparent) resistance of two resistors in parallel, just divide the product of the resistance values by their sum. Let's say you've got a 3-ohm resistor in parallel with a 6-ohm resistor. The total resistance is 6*3/(6+3) = 18/9 = 2. So, the total resistance of those two resistors in parallel is two ohms. If you've got two identical resistors in parallel, the resistance is exactly half the value of one resistor. Two 10-ohm resistors in parallel have a resistance of five ohms. Two 100-ohms resistors have a resistance of 50. Two 150Kohm resistors have a value of 75Kohm. If you've got a bunch of resistors in parallel, here's what you do. Add up all the reciprocals of the resistance values. Then find the reciprocal of that sum. Your answer should be less than the lowest-valued resistor in your R-ladder. If it's not, you hosed the calculation. Try the following: Calculate the resistance of the following resistors in parallel (assume ohms for each): 2, 4, 8, and 16. You should come out with 16/15 ohms, which equals 1.067 ohms. I know some of you want to see the math. First, add up the reciprocals: 1/2 + 1/4 + 1/8 + 1/16 = 8/16 + 4/16 + 2/16 + 1/16 = 15/16. Next, take the reciprocal of that answer: 16/15 = 1 and 1/15 = 1.067 ohms. If you need more help, use the discussion page, but leave a note on Schnazola's personal page so I know to look.

# What happens to resistivity of a wire when it is double folded?

Nothing. Resistivity is a physical characteristic of a material. It's not affected by its shape, etc.

# When a wire is made smaller the resistance increases what happens to the electics current?

as with any electrical system if resistence is increases then current and voltage will be reduced.

# As a wire increases in length what happens to the resistance in the circuit?

the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease) Since resist…ance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.

# 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.RAO Answer If you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothing happens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).

# Why does the resistance of wire increase as you increase the length?

Wire has a specific resistance per distance. So if you increase the distance, the resistance of that particular wire will be greater.

# What happens to the resistance as the area increases?

Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
