Questions & Step-by-Step Solutions
If two resistors of resistivity ρ are connected in series, what is the total resistivity of the combination?
Step 1: Understand what resistivity (ρ) means. It is a property of the material that determines how much it resists the flow of electric current.
Step 2: Recognize that resistivity is not the same as resistance. Resistance depends on both the resistivity of the material and the dimensions (length and area) of the resistor.
Step 3: Know that when resistors are connected in series, the total resistance increases, but the resistivity of the material remains the same.
Step 4: Conclude that the total resistivity of the combination of resistors in series is still the same as the resistivity of each individual resistor, which is ρ.
