Question

The reciprocal of resistance is called:
A. Conductance
B. Friction
C. Specific Resistance
D. Reaction

Answer 1

Hint: Conductance is the ease by which charge can flow in any conductor. Remember resistance is the property which stops the flow of charges to generate current.

Complete step by step answer:
Basically what do you mean by resistance? To know all about resistance we need to focus on two important terms of electricity that are Electric Current and Potential Difference. When the electric charges flow in a conductor they generate an electric current. We also know that the electric charges flow just because of the potential difference between them.
Resistance is directly linked with the electric current and the potential difference. In 1828 German physicists showed this relation by giving ohm's laws where they told that the potential difference is directly proportional to the electric current and he even gives the proportionality sign R which he termed as resistivity.
If we define resistance it is the property which stops the flow of charges to generate current or they make hindrance in the motion/flowing of electric charges and if there is a hindrance in the flowing of electric charges so less current will be generated so this means that if there is a high resistance less current will be generated and low resistance results in the generation of more current.
Resistance hardens the generation of electric current whereas conductance makes the flow of charge easy that is it makes the generation of electric current easy. Hence it is clear that the conductance is the reciprocal of resistance.
So, the correct option is a.

Note: Always remember that reciprocal means the just opposite characteristics.
Friction is force that resist the relative motion of surfaces sliding over each other.
Specific resistance is related to resistance, it is the resistance per unit length and unit cross-sectional area.
Reaction is actually an action that takes place when something happens.
