which factors affect the resistance of a material? select three options. length current thickness temperature voltage
Answer
Brief Explanations:
The resistance formula is $R = \rho\frac{l}{A}$, where $l$ is length, $A$ is cross - sectional area (related to thickness), and $\rho$ is resistivity which is affected by temperature. Current and voltage do not affect the resistance of the material itself but are related to Ohm's law ($V = IR$).
Answer:
A. length, C. thickness, D. temperature
