9 Application And Recommended Usage Of Current Sensing

Resistors are devices that deliberately.

Example of a resistor. You can for example use a variable resistor to control the loudness of an amplifier the pitch of a musical tone or the speed of a motor. Types of variable resistors potentiometers. Download basic electronic components pdf a mini ebook with examples that will teach you how the basic components of electronics work.

Determine the total resistance of this series parallel combination of resistors. Varying resistance changes the amount of current flowing in a circuit. Filament in a bulb wire paper clip what is an example of a resistor resistance reduces the flow of current in a conductor.

An example of an smd resistor on a pcb is given in the picture below. Figure 13 circuit for example 8. The marking 331 means that the resistance has a value of 33w x 101 330w.

If you add a resistor in series with a circuit the current in the circuit will be lower than without the resistor. The resistor is a component that resists current. The size of the component length and width is standardized as well and is referred to as resistor package.

But what about the resistor. A potentiometer is a 3 terminal variable resistor. If we connected that led up directly to a 12.

Here are examples of resistors. By adjusting the wiper terminal it can be used to represent a wide range of resistances in a circuit from anywhere near 0w to the specified resistance rating of the potentiometer. An led is a small red light such as the one on the front of most tvs and requires 20 volts and 002 amps to operate correctly.

The tolerance of a resistor is the difference between the preferred value ie 100 ohms and its actual manufactured value ie 1036 ohms and is expressed as a percentage for example 5 10 etc and in our example the actual tolerance is 36. Some types of resistors are variable letting you set their resistance by sliding a slider or turning a knob.
