When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a parallel circuit add up to the supply current.

First, incorporate a digitally controlled variable resistor, such as a DS1859, into the regulator circuit of Figure 1 by placing it in parallel with R 2 (Figure 2). A temperature-indexed look-up table ...

There are a variety of electrical circuits. We differentiate them through various diagrams and how electrical components connect in a circuit.

A simple series resistor circuit should suffice. Fig. 7 is a classic voltage divider. The output voltage will be at half of the input voltage, which is 6 dB lower than the input. Fig. 7: Voltage ...

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

Very often when simulating an electrical circuit in SPICE, there is a need for a variable passive element such as a resistor, a capacitor or an inductor.
