# What would happen if the length of wire increase what happens to the resistance?

resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.

# 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 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 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 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 (MORE)

# 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 (MORE)
