: To control the charge or discharge current and stabilize load. ? Motor: To control the rotation speed, either steady or variable. Re: Current sensor When loading current is low, current flows in direction 1. When loading current is increased to a certain level and turns Tr2 on, current flows...

Think of the IO port as a variable resistor that regulates the current to 4-20 ma in the loop. All the other. devices in the loop are represented as a resistor equal to the input resistance of all the devices combined. This maximum allowable value for this resistance depends on the power supply...

A PIN diode is essentially a variable resistor. To determine the value. of this resistance, consider a volume comparable to a typical PIN. diode chip, say 20 mil diameter and 2 mils thick. This chip has a. DC resistance of about 0.75 M O. Note: 1 mil = 0.001 inches. In real diodes...

...very simple circuits, not much more than a high-current rheostat (variable resistor) wired in series with the lamp. For low-light conditions, it was adjusted to a high resistance, reducing the current through the lamp filament. For high-light conditions, it was adjusted for a low resistance increasing...

...the data to the fuel gauge or digital instrumentation to display the signal generated level. One common liquid level sender is a 33-240 Ohm resistive float sender.

...float level sender. It consists of a float attached to an actuating arm (rod) with a variable resistor (potentiometer) mounted at the end of this rod. The resistive float water level sender interfaces with the gauge via a wiper that slides across the resistive material of the potentiometer....

When an electric motor is driven by a variable frequency drive (VFD), electric power delivered to the motor is regenerated while the motor decelerates by applying negative torque to the motor shaft. Usually energy storage capacity inside the VFD is very limited so regenerative energy should...

The simplest and least expensive solution is to connect a resistor from the VOUT Adjust pin to the minus (-) reference point or to the plus (+) reference point (positive point where the feedback RF resistor is connected. When a variable voltage source, such as a digital-to-analog converter (D...

Linear regulators (or voltage regulators) act as a series variable power resistor when they are connected between an unregulated voltage source and a load. Linear regulators are used to provide voltage stability (regulation) for the load. However do not confuse linear regulators with switching...
