To solve problems on internal resistance it should be remembered that such circuits involve using a series circuit with the internal resistance and the load.

Light-emitting diodes (LEDs) give off light and are often used for indicator lights in electrical equipment such as computers and television sets. The diode has a very high resistance in one ...

In other words, with the perfect setup, you could put a digital panel meter that reads the voltage in the circuit, and read the resistance directly. Zeroing it out would require more effort to get ...

which may cause a resistance to current flow and create wasted power in the form of heat. But a 30 percent reduction in one’s ...

the material can reversibly alternate between different levels of electrical resistance. In the new study, the researchers showed that alongside electrical resistive switching, a thermal resistive ...

I AM indebted to Mr. Herbert Tomlinson for drawing my attention to his most interesting comparisons between the behaviour of carbon and of metals in respect of change of electric resistance under ...
