The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

Negative differential resistance circuit built with BJTs and corresponding circuit symbol I just made up. With this in mind, back in 2002, ...

the total resistance of the circuit is reduced as the current can follow multiple paths; Extended syllabus content: Resistance in parallel. If you are studying the Extended syllabus, ...

This simple but clever continuity tester sports two LEDs: RED LED = circuit resistance is < approx 10K, GREEN LED = circuit resistance <10Ω. It consumes approx 8mA from a 9V battery. When not ...
