BU-902: How to Measure Internal Resistance
8.3: Ohm''s Law
Ohm''s Law. The current that flows through most substances is directly proportional to the voltage (V) applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: [I propto V . label{20.3.1}]
Electrical resistance and conductance
OverviewIntroductionConductors and resistorsOhm''s lawRelation to resistivity and conductivityMeasurementStatic and differential resistanceAC circuits
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 proportional to how much flow occurs for a given pressure, and resistance is proportional to how much pressure is required to achieve a given flow. The voltage drop (i.e., difference between voltages on one side of the resistor and the other), not …

Wire Resistance Calculator
Resistance and resistivity are two similar properties of an object. However, they are not precisely the same. Resistivity ρ describes the opposition to the flow of charged particles through an object, and it''s an intrinsic property of the material which doesn''t depend on the wire''s dimensions.. Similarly, resistance σ refers to how strong a wire of …
