Question

Do bends in a wire affect its resistance?

Answer 1

no it can only change the flow of current

Answer 2

thank you sachin

Answer 3

Resistivity is an atomic level effect so there Might be a very tiny change if the atomic structure changes but it would be less than normal variation due to temperature

It affects the wire's inductance, but not its DC resistance.

for all practical purposes NO

remember V = IR is NOT a law like F =mA
because,
it is an experimental relationship for a particular material
