A wire of length L and radius r has a resistance R. If the length and radius of this wire are doubled, the new resistance: remains the same. doubles. quadrables. drops to 1/2 its original value. drops to 1/4 its original value.
A wire of length L and cross-sectional area A has resistance R. What will be the...
A wire of length L and cross-sectional area A has resistance R. What will be the resistance Rstretched of the wire if it is stretched to twice its original length? Assume that the density and resistivity of the material do not change when the wire is stretched.
The resistance R of a wire of length l and uniform area of cross-section A is...
The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.
A wire with a resistance of 6.0 ohms is drawn out through adie so that its...
A wire with a resistance of 6.0 ohms is drawn out through adie so that its new length is three times its original length. Findthe resistance of the longer wire, assuming the resistivity anddensity of the material remain the same.HELP!!!!!!!!!!!
The resistance R of a wire varies directly with the length L of the wire and...
The resistance R of a wire varies directly with the length L of the wire and inversely with the square of its radius r. A wire with a length of 350 cm and a radius of 0.4 cm has a resistance of 16 ohms. Determine the resistance of a 500 cm piece of similar wire with a radius of 0.35 cm. Round your final answer to four decimal places and be sure to include units.
A wire with a resistance of 50 Ω is drawn through a die so that its...
A wire with a resistance of 50 Ω is drawn through a die so that its new length is 2 times its original length. Find the resistance of the longer wire, assuming that the resistivity and density of the material are unchanged.
