For a fixed resistor, the voltage is directly proportional to the current. Doubling the amount of energy into the resistor results in a current twice as fast through the resistor. This relationship is called Ohm's Lawand is true because the resistanceof the resistor is fixed (because the temperature does not change). See more In a filament bulb, the current does not increase at the same rate as the voltage. Doubling the amount of energy does not cause a current twice as fast. The more energy that is put into the bulb, the harder it is for the current to … See more A semiconductordiode only allows current to flow in one direction. If the potential difference is arranged to try and push the current the wrong way (also called reverse-bias) no … See more The resistance of a thermistor varies with temperature. As the temperature increases the resistance decreases. The resistance of an LDR (Light Dependent Resistor) varies with … See more WebLearn about and revise giant covalent molecules with this BBC Bitesize GCSE Chemistry (AQA) study guide. phillip clark
