  • Investigating the I-V characteristics of electrical components . . .
    For 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
  • IV Graphs - AQA GCSE Physics Revision Notes
    The current through a conductor is directly proportional to the potential difference across it Electrical conductors that obey Ohm's Law are referred to as ohmic conductors
  • Fixed Resistor | Resistor Types | Resistor Guide - EE Power
    What is a Fixed Resistor? Fixed value resistors have a defined ohmic resistance and are not adjustable Fixed resistors are the most commonly used resistors and in general one of the most used electronic components
  • Ohmic Non-Ohmic Conductors - Differences, Examples and V-I . . .
    Electrical conductors which obey Ohm’s law are called Ohmic Conductors The resistance of ohmic conductors is independent of applied voltage i e , the resistance remains constant regardless of the magnitude of the applied voltage They have a linear relationship between the current and the voltage
  • What is an ohmic resistor? How to check if a resistor is ohmic? - MyTutor
    An ohmic resistor is a resistor that obeys Ohm's law V = IR (voltage = current x resistance) Therefore, if the voltage in such element is increased by n number of times, by the same number n has to increase the current To determine if a resistor is ohmic, voltage in a resistor needs to be changed and both voltage and current have to be meassured
  • Electricity - 2. 1. 4 Resistors (GCSE Physics AQA) - Study Mind
    Resistance is measured in ohms (Ω) There are two different types of resistors, which are both able to slow down the current in a circuit: Fixed resistors – fixed resistors have a constant value Therefore, the resistance provided by a fixed resistor is constant
  • Ohms Law and resistance - Revise: Ohms Law - National 5 Physics . . . - BBC
    Fixed-value resistors do not change their resistance, but with variable resistors it is possible to vary the resistance and the current through it, not just any values that you see in the
  • Ohmic Non-Ohmic Conductors - Electronics Notes
    They are used within electronic circuit designs to provide a fixed level of resistance within a circuit to set voltages, limit current and the like There are some forms of resistor that are non-ohmic that are used for some specialised applications
  • Ohms Law I-V Characteristics | OCR AS Physics Revision Notes 2015
    For a conductor at a constant temperature, the current through it is directly proportional to the potential difference across it Constant temperature implies constant resistance
  • Resistors - pfnicholls. com
    Therefore an ohmic resistor is a component that obeys Ohm's Law such that the current and voltage are directly proportional and the resistance remains constant A good example of ohmic components are fixed value resistors and lengths of wire at a fixed temperature
