Graph of a fixed resistor
WebA 12 V battery is in series with an ammeter, a 2Ω fixed resistor and a 0 − 10Ω variable resistor. High-resistance voltmeters P and Q are connected across the variable resistor and the fixed resistor, respectively, as shown. The resistance of the variable resistor is changed from its maximum value to zero. WebJan 4, 2024 · 1) Fixed Resistors. In these types of resistor, whose resistance value cannot be changed are called fixed resistors. Based on the construction and material used, fixed resistors are further classified into: …

Once you have done that, you have a simple 4-resistor network to solve. Solve this at as many pot settings as you like to get a graph of voltage as a function of pot position.
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 … WebSep 22, 2024 · As their respective names suggest, a fixed resistor has a single fixed value of resistance, whereas a variable resistor has resistance value over a defined range.

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. 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 …
