Graph of a fixed resistor
WebFixed Resistors & Wires. The current through a fixed resistor or a wire increases as the potential difference (or voltage) across it increases; In other words, current is directly proportional to the potential difference for a fixed resistor (or a wire). This relationship is true because the resistance of the fixed resistor (or wire) stays constant; An IV graph … WebFor a fixed resistor, the potential difference is directly proportional to the current. Doubling the amount of energy into the resistor results in a current twice as fast running through the resistor.

JizzaDaMan said: Well if the resistance of the lamp is ΔV/ΔI at any point on the graph, then given that the relationship between the voltage and current for the lamp is non-linear, this will not be V/I which by Ohm's law is the formula for resistance. The original definition of Ohms Law was just the linear equation V=IR.

A potential divider circuit consists of fixed resistors of resistance 2.0Ω and 4.0Ω connected in series with a 3.0Ω resistor fitted with a sliding contact. These are connected across a battery of e.m.f. 9.0 V and zero internal resistance, as shown.
WebMar 31, 2024 · A resistor is an electrical device that resists current, and the difference between ohmic and non-ohmic resistors relates to how the resistor reacts to different types of current that pass through it. In an ohmic resistor, the resistance provided is the same regardless of the type of current that passes through the device. In a non-ohmic … graphic art knifeWebA voltage divider is a simple series resistor circuit. It's output voltage is a fixed fraction of its input voltage.
