WebJan 24, 2024 · The conductivity of a material is a measure of the ease with which electric current can flow through a material. It is also known as specific conductance. The … The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction. The SI unit of electrical … See more In the hydraulic analogy, current flowing through a wire (or resistor) is like water flowing through a pipe, and the voltage drop across the wire is like the pressure drop that pushes water through the pipe. Conductance is … See more For many materials, the current I through the material is proportional to the voltage V applied across it: Other components and materials used in electronics do not … See more The resistance of a given object depends primarily on two factors: what material it is made of, and its shape. For a given material, the resistance is inversely proportional to the cross-sectional area; for example, a thick copper wire has lower resistance than an … See more Many electrical elements, such as diodes and batteries do not satisfy Ohm's law. These are called non-ohmic or non-linear, and their See more Substances in which electricity can flow are called conductors. A piece of conducting material of a particular resistance meant for use in a circuit is called a See more An instrument for measuring resistance is called an ohmmeter. Simple ohmmeters cannot measure low resistances accurately because the resistance of their measuring leads causes a voltage drop that interferes with the measurement, so more accurate … See more Impedance and admittance When an alternating current flows through a circuit, the relation between current and voltage across a circuit element is characterized not only by the ratio of their magnitudes, but also the difference in their phases. … See more WebLearn how to calculate resistance in series and parallel circuits ...
