Graph of a resistor
Non-linear circuit elements include fixed resistors that become hot, and filament bulbs which become hot and glow. The shape of the I-V graph changes as the temperature of the component increases. When the component becomes hotter, the atomsin the metal latticevibrate more. More collisions occur … See more A diodehas a very high resistance in one direction. This means that current can only flow in the other direction. See more Light dependent resistors or LDRsare made of semiconductormaterial. Their resistance decreases as the light intensity increases. LDRs can be used to switch lights on or off … See more Web1 The resistance of a Light Dependent Resistor (LDR) is affected by the amount of light that shines on it. A student investigates this relationship using the circuit shown. A (a) (i) The student uses a voltmeter to measure the voltage across the LDR. Add this voltmeter to the circuit diagram. (2) (ii) Explain how the student can work out the resistance of the LDR …
