Question

choose the correct answer. which of these wires has the lowest resistance? brown blue green the green wire has a length of 50 cm the brown wire has a length of 40 cm the blue wire has a length of 30 cm shorter wires have a lower resistance longer wires have a higher resistance

Explanation:

Step1: Recall the relationship between wire length and resistance

Shorter wires have lower resistance.

Step2: Compare the lengths of the wires

Green wire is 50 mm, Brown wire is 40 mm, Blue wire is 30 mm.

Step3: Determine the shortest wire

Since 30 mm (Blue wire) < 40 mm (Brown wire) < 50 mm (Green wire).

Answer:

Blue
