Conductivity
Über den Vortrag
Der Vortrag „Conductivity“ von Jared Rovny, PhD ist Bestandteil des Kurses „Circuit Elements“.
Quiz zum Vortrag
Which of the following is true about the conductivity of a material?
- It is independent of the geometry of the material.
- It depends only on the length of the material.
- It depends only on the cross-sectional area of the material.
- It depends on the length and cross-sectional area of the material.
- It halves when the length of the material is doubled.
If you already know the length and cross-sectional area of a material, what 2 quantities do you need to know to determine the resistivity of a material?
- The current flowing through the resistor and the voltage applied across the resistor
- The length of resistor and voltage applied across the resistor
- The cross-sectional area and voltage applied across the resistor
- The current flowing through the resistor and the voltage of a battery that is not in parallel with the resistor
- The change in current and voltage across the resistor
How can you calculate the conductivity of a material if you know its resistivity?
- By taking the reciprocal of resistivity
- By taking the negative of resistivity
- By taking the square root of resistivity
- By squaring the resistivity
- By taking the reciprocal squared of resistivity
