Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more th… ...

Thermocouples generate voltage as a function of the temperature difference between the tip (thermocouple temperature) and the electrical connection on the circuit board (cold junction temperature). In ...

The voltage across the thermistor will be 5 * (500/(4700+500)) or about a half volt. I mentioned that most thermistors you’ll find in a printer read 100 kΩ at room temperature. You might think ...

Save guides, add subjects and pick up where you left off with your BBC account. The two resistors may have fixed values or one may be an LDR, a thermistor or other input device. The supply voltage ...
