Question

A metallic wire of resistance 12Ω is bent to form a square. The effective resistance between two diagonal points would be

Answer 1

Answer:

Hey mate

Here is your answer mate

Assuming the one 12 ohm resistor is divided into four (4) each, three (3) ohm resistors. the configuration is effectively a series/parallel arrangement. There are two series pairs:

Rs= 3 + 3 ohms = 6 ohms.

These two 6 ohm resistors can then be considered to be in parallel:

1/R - 1/6 + 1/6 = 2/6 = 1/3, so that:

R = 3 ohm, but with a higher wattage rating
