An electrician finds that a 1.1 m length of a certain type of wire has a resistance of 0.17 Ω . What is the total resistance of the 119 m of this wire he plans to use? Answer in units of Ω.

A copper wire has a resistivity of 1.723 x 10-8 Ω-m and a cross-sectional area of 9.5 mm2. Calculate the length of the wire in m when its resistance is 3.2 Ω.

A copper wire has diameter 0.5 mm and resistivity of 1.6 x 10-8 Ω m. What will be the length of this wire to make its resistance 10 Ω ? How much does the resistance change if the diameter is doubled

The resistance of a wire of 0.01 cm radius is 10 Ω. If the resistivity of the material of the wire is 50 × 10-8 ohm meter, find the length of the wire.

A transmission line cable consists of 26 strands of identical copper conductors, each 1.255 mm in diameter. The length of the cable is 10 km, but because of the twist of the strands, the actual length of each conductor is increased by 5%. If the resistivity of the copper is 1.72 x 10-8 Ω.m, what is the resistance of the cable in ohms?
