No, higher specific resistance means lower conductivity. Specific resistance is the resistance of a material per unit length and cross-sectional area, so a higher value indicates that the material resists the flow of electric current more effectively. Conversely, materials with lower specific resistance values are more conductive.
What else can I help you with?
Why does the length of wire affect the resistance?
the longer the wire, the more mass the electrons have to travel thru. the more they have to travel thru, the more resistance. (and the resultant heat) the more electrically conductive the wire, the less resistance.
How does the 4 factors affect the resistance?
The four factors that affect resistance are material, length, cross-sectional area, and temperature. Resistance increases with longer length and higher temperature, and decreases with greater cross-sectional area and more conductive material. These factors impact the ability of a material to impede the flow of electrical current.
When wire is thicker its resistance is?
When a wire is made thicker it's resistance decreases.
Which coin is more conductive?
Silver is more conductive than copper, followed by gold. Silver has the highest electrical conductivity among all metals, making it a preferred choice in many electronic applications. Copper is more commonly used due to its balance of conductivity and cost-effectiveness. Gold, while less conductive than silver and copper, is preferred in certain applications due to its corrosion resistance.
How does the resistance change in LDR with dark?
In the dark, an LDR (Light Dependent Resistor) will have a high resistance value as it is not exposed to light. When exposed to light, the resistance of an LDR decreases significantly due to the photoconductivity effect, making it more conductive.
Is shorter more conductive or longer more conductive?
Other things (cross-section, material) being equal, a longer piece of conductor has more resistance (i.e., less conductance) than a shorter piece.
Why does the length of wire affect the resistance?
the longer the wire, the more mass the electrons have to travel thru. the more they have to travel thru, the more resistance. (and the resultant heat) the more electrically conductive the wire, the less resistance.
Why does largest R dissipate more power?
That's not always the case. One formula for power dissipated is:P = IRSo, a higher resistance means that more power is dissipated - if the current is the same. The reason for this is precisely that resistance is related to the conversion of electrical energy into heat.However, if you put a higher resistance across a specific voltage, you'll get less power dissipation, not more, since less current will flow at a higher resistance.
Does a higher number of conducitvity mean is conductive?
Yes, the higher the conductivity concentration the higher the conductivity value in the material. Some times the conductive particles are surrounded with insulating materials which cut the conductive paths between the electrodes and as a result it stops the increase in the conductivity values to a certain limit according to the structure (texture) in the material.

What will wear better non conductive or conductive rubber?
Non-conductive rubber will typically wear better in terms of longevity and durability compared to conductive rubber. Conductive rubber may be more prone to wear and tear over time due to its electrical properties, which can lead to degradation of its conductivity. However, the specific wear characteristics can also depend on the specific properties and intended use of the rubber material.
Is the body more conductive than metal?
No, metal is generally more conductive than the human body. Metals such as copper and aluminum have much higher conductivity compared to the human body, which means they can more easily carry electric current.
What is more electrically conductive copper or iron?
Copper is more electrically conductive than iron. This is because copper has a higher conductivity due to its atomic structure, allowing electrons to move more freely through the material compared to iron.
How does the resistance change in LDR with dark?
In the dark, an LDR (Light Dependent Resistor) will have a high resistance value as it is not exposed to light. When exposed to light, the resistance of an LDR decreases significantly due to the photoconductivity effect, making it more conductive.
How can we design a circuit with less resistance to allow more current flow?
To design a circuit with less resistance for more current flow, you can use conductive materials with lower resistance, increase the thickness of the wires, and minimize the length of the wires. Additionally, using components like resistors with lower resistance values can also help reduce overall resistance in the circuit.
